A picture says a thousand words, they say. If getting those pictures online is troublesome, some of those words might be a little choice.
Gallery has been an integral part of our community suite for just about as long as T1 Tech Mark Higgins can remember (and he has many years of memories). It has seen many interfaces changes as the years have rolled by. The most recent version received a fair amount to feedback on usability.
We've listened. We've re-engineered most of Gallery's key interfaces to make uploading new images to your community frictionless.
Lets take a look through the major changes.
Improved submission process
Submitting images has to be simple or else users will give up and your gallery will be underutilized. We have spent a lot of time simplifying and speeding up the submissions process for your users. The first thing that will be noticed is that the submission process is not presented as a wizard anymore, and the choice to submit to a category or album has been significantly cleaned up and simplified.

 
Choosing a container
Here, I have chosen the category I wish to submit to, so now I am asked if I want to submit directly to the category, if I want to create a new album, or if I want to submit to an existing album.  Choosing one of those last two options will load the appropriate forms to create an album or select an existing album, respectively.
Afterwards, the modal expands to full screen and you will naturally select your images next, and there's a lot to talk about here.
 

Overhauled submission interface
First and foremost, the interface has changed significantly to both simplify the UI and to make actually using the interface easier. When you click on an image, the form is loaded to the right immediately without an AJAX request needed to fetch the form.
In addition to quickly setting the credit and copyright information for all images at once, you can now set the tags for all images quickly and easily without having to edit each image individually.
Images support drag n drop reordering in the uploader here, which means that you can drag n drop images to different positions to control their order. Many users previously would name images "Image 1", "Image 2", and so on, and then set their albums to order images by name in order to control the order the images were displayed in. This is no longer necessary now that you can manually reposition the images.
The default description editor is a pared down textarea box, but you can still use the rich text editor if you wish. The ability to enable maps for geo-encoded images and to upload thumbnails for videos is still supported as well, and those options will show up when appropriate in the right hand panel.
The 100 image per submission limit has also been lifted. You can now upload many more images in one go with no hard limit imposed.
Upon clicking submit images, you will see the typical multiredirector to store all of your images, however you will notice that it processes much faster than it did in 4.2 and below.
Better submission control
Administrators can now configure categories such that can accept only images, only albums, or both. This means you can now create categories that cannot be submitted to directly, and you can create categories that albums cannot be used with. This is a feature that has been oft-requested since the release of 4.0, and we are happy to report that it will be available in our next release.
Additionally, album creators (if permitted) can also now create shared albums.  When you create a new album, you can now specify (under the Privacy menu) who can submit to the album, with your available options being:
Only me Anyone Only the users I specify Only the groups I specify Prior to 4.3, albums have always been owned by one user and only that user could submit to them. Invision Community 4.3 will open up albums so that anyone can submit to them, dependent upon the album creator's preferences and needs.

The choice is yours as to who can submit to your albums
New image navigation
Another major change with Gallery 4.3 is that clicking an image now launches that image in a lightbox to view it and interact with it. This lightbox is context-aware, allowing you to visit the next and previous images in the listing, whether that is a category or album listing, or the featured images or new images listings on the Gallery homepage, for example.
 

The new image lightbox
Firstly, I will note that you are seeing the image here with my mouse cursor over the image area, exposing the title, tags, and some various buttons. When you mouse away from the image those overlays fade away to highlight the image itself better.
As you can see, you can navigate left and right here to view the next and previous image in this context, and you can otherwise interact with the image as you would have if you had visited the older-style image view page (including the ability to rate, review and comment).
The new Gallery release will introduce a new advertisement location in the right hand column to allow you to show advertisements, even in the lightbox.
If you follow a link to a full image view page, the lightbox will automatically launch when the page loads, still allowing you to interact in a familiar manner. Additionally, if you move through enough images in the lightbox to reach a new page (for example, if you click on the last image in the album listing and then click on the next image button), the listing itself behind the lightbox will update for easier usability if the user closes the lightbox.
One final thing to note is that the interface has been made more mobile friendly, particularly through the introduction of swiping support. You can swipe left and right in the lightbox, and in image carousels, to see the next and previous images.
Notable performance improvements
As we mentioned at the beginning, we recognize there is a balance between performance, usability, and attractiveness, particularly with regards to an image Gallery. For that reason, we have made Gallery's performance a major focus in 4.3, and have implemented some changes that bring with them a noticeable performance improvement.
Firstly, we have adjusted the software to only store two copies of an image (in addition to the original), instead of four. In previous versions, we stored a thumbnail, a small copy, a medium copy and a large copy of an image, all of which arbitrarily sized and designed to best meet our layout needs without showing an image too large or too small in a given space. We have simplified this vastly by storing a slightly larger "small" image, and storing a large copy. Diskspace usage is reduced dramatically as a result, and bandwidth usage is actually lowered as well since only two copies of an image need to be delivered to the browser instead of four.
Next, we have implemented prefetching of the 'next' and 'previous' pages when you launch the lightbox image view. This means that when a user navigates to the next image in the lightbox, it loads immediately instead of waiting for the content to be fetched from the server. From a UX perspective, this provides a much snappier and responsive interface, making users more apt to interact with the site.
We have additionally sped up the submission process as previously mentioned. The order of execution for certain events that must happen during submission has been moved around a bit, resulting in a faster experience for the end user actually submitting the images.
Because we know the details matter, we have implemented other smaller improvements as well. For example, the link to rebuild images in the AdminCP previously resulted in a redirect process that rebuilt the images while you waited, but now a background task is launched so that you can continue with what you were doing while the images get rebuilt in the background.
From start to finish, the Gallery UI and UX has been touched on and improved, and we hope you enjoy these improvements when you start using the new version.

This is an entry about our IPS Community Suite 4.2 release.
The ability to automatically promote users from one group to another based on set parameters has been a staple of community software for some time. Traditionally, the most common determination of promotion has been post count. Additionally, the 4.x Community Suite supports promoting members automatically based on the time elapsed since the user joined the site and based on their total reputation count.
With 4.2, we have completely overhauled and enhanced the group promotion feature bringing many new options to administrators looking to promote members through different group levels.
To start with, the group promotion options have been removed from the groups configuration pages into their own area.

Group promotion rules overview page
You will notice that rules are no longer strictly tied to a single group, and that rules can be sorted however you desire. When you create and edit rules, you can choose which groups the rule applies to, what parameters the user needs to meet in order for the rule to be activated, and then finally, which primary and secondary groups the user will be moved in to. You can also configure the rule to remove specified secondary groups, which can be useful if one rule adds a secondary group for users, and then the next rule should change them to be part of a different secondary group (i.e. add a new secondary group, but also remove the previously awarded secondary group).
The system uses the same member filters available when configuring bulk mail, and we have made some updates to the member filters area (and have introduced some new filters) in this release as well. For example, you can create a rule that only applies to members who have won the daily leaderboard at least once, or members who have created a blog.

Some of the group promotion filters, which are also available when sending bulk mails
Any time a member account is updated for any reason (a new visit, editing the member, the member makes a new post, etc.), the software will loop through all configured rules and the last rule in the list that matches the member will be applied. This approach allows you to create promotion levels, for instance when a member reaches 100 posted content items they will be promoted to a new group, and when they reach 1000 posted content items they will be promoted to yet a different new group.
Groups can be wholly excluded from any promotion rules, which is useful when you have administrator and/or moderator groups and you want to ensure that they are never moved to a different group. These groups will be disabled from selection when configuring group promotion rules, and these groups will be ignored if "any group" is selected for a promotion rule.
Finally, if a user is moved to a new primary group by Commerce because they have purchased a product which moves them to a new group, they will also be excluded from group promotion rules (however, Commerce purchases that only adjust secondary groups will not exclude users from being checked by group promotion rules).
 
Developer note: You can add your own filters for group promotion rules (and bulk mails) by adding MemberFilter extensions in 4.2, available in the Developer Center for your application.

This is an entry about our IPS Community Suite 4.2 release.
When you have a diverse range of topics within your community, it makes good sense to separate topics within forums and categories. This will ensure that the viewer can find relevant content by scanning the list of forums first.
If you have a more focused community with fewer forums, presenting your community with a list of them can be daunting. This is especially true for less experienced visitors raised on social media.
Fluid forum view allows your visitors to get right to the meat of your community; the topics.
A fan site for a band is a good example of a community that will benefit with fluid view. There will likely be forums for album reviews, tour dates, general discussion and so on. Even though there are many forums, the common topic is the band. This makes fluid view ideal as your members can see all those related topics in one view. If your members wanted more specific topics, they could select a single forum to view.
Let us take a look at fluid view in action. We will then break it down and explain how it works in more detail.

 
The video shows the topic list and the forum filter box. As you can see, it is easy to change the topic list by changing the selected forums. This view replaces the traditional list of categories and forums.

 
Of course, you can permit your members to change the view to better suit their way of working.

 
You will notice a "grid" option. We have moved the grid forum theme setting into the main forum settings. This makes it an option for your members to choose, if the administrator permits it.

 
You have full control over the display options. This screenshot shows that the control panel option to choose the default view. There is also an option to control which views your members can select. You may also decide to not allow your members to switch views at all. This will ensure that they all use the view you choose.

 
You may have spotted that forum names have a colored background in some screenshots. We added the ability to define a feature color per forum. This feature color helps the forum stand out in a more visual way. This is especially useful when you select many forums in a single view.

 
This feature color also works on the table view.

 
We added a feature color hint to topic view to enforce the association between the forum and its color.
 

 
This screenshot also shows the removal of the forum breadcrumb in fluid view mode. Fluid view remembers your last forum selection so you don't lose your place when you go back to the listing.
The benefit of this feature is easy to see. It removes a potential barrier of entry for your audience. It puts the spotlight on topics themselves, and not the hierarchical forum structure. Your members will enjoy viewing many forums at once and switching between them without leaving the page.
We hope that fluid view is an asset to your community and your members enjoy this new functionality.
Technical notes.
The database stores the members' view choice. This remembers the selection across devices. Guests are not permitted to change between views.
 

This is an entry about our IPS Community Suite 4.2 release
In previous versions of IPS Community Suite we have had an account history feature in our Commerce application. This feature showed many important actions that may be relevant to the customer such as when an invoice was generated or when a customer changed their account details.
In IPS Community Suite 4.2 we have expanded this functionality and moved it into the core functionality of the suite.

Member History Member Overview
Member actions that will be logged include (but are not limited to)
Email address change Display name change Password change Account merge Primary group change (The reason will be shown when triggered by an automatic group promotion) Secondary group change Flagged/Unflagged as spammer Multi-Factor Authentication (Enable / Disable / Opt-out) Social media (Twitter, Linked In, Facebook, Google, Twitter, IPS Connect) for enabling, disabling and which (if any) were used to register an account. The Commerce customer account page will now show actions that may be related with a transaction or account.

Member History on the Commerce customer view
Discoverability
Each action is also discoverable via the IP Address tools built into IPS Community Suite 4

Member History in IP Search
We’ve also made the data table filterable

Member History Search
Notes for developers:
The new Member History system has been designed with interoperability in mind. In IPS Community Suite 4.2 you will be able to integrate your own applications into this system. Member History replaces the display name changes system.

IPS Community Suite has supported drag and drop uploading to the attachments area at the bottom of the editor since 4.0. In 4.2 we're pleased to add the ability to drag and drop right into the editor, so you can drop your attachment exactly where you want it to show without having to add it afterwards.

Drag and drop into editor
If your browser and OS supports it you can also copy and paste, either from the desktop or from other content on the web:

Improved Stripe Integration
Stripe is a popular payment gateway that supports card payments. In IPS Community Suite 4.2 we have made some improvements to our integration:
When viewing a transaction in the AdminCP, it will show the last 4 digits of the card used, and the result of Stripe's risk evaluation. More information is sent to Stripe for easier cross-reference between Stripe's control panel and your AdminCP. This includes the customer's name, billing and shipping addresses, email address, associated transaction/invoice/customer IDs, and the invoice title.

Anti-Fraud Improvements
Anti-Fraud Rules now have some additional filters:
Products being purchases includes... Account was registered more/less than [x days] ago Customer is/isn't in group Customer has previously spent more/less than Time since last purchase is more/less than [x days] ago Custom profile fields (both at member and customer level) IP address is x (exactly, contains or matches regular expression) Customer has previously made transactions that failed (opposed to "were blocked by fraud rules") Email address matches regular expression

MaxMind per gateway
A new setting has been added that allows you to run MaxMind only against transactions using particular payment gateways.

Transaction Search
You can now enter the transaction ID provided by the payment gateway in the AdminCP search box to find a transaction.

Renewal Savings
If you have a product with multiple renewal terms, a new setting allows you to show alongside each option how much is saved. This can be shown either as a monetary value, or as a percentage.

This is an entry about our IPS Community Suite 4.2 release
We are happy to introduce several changes to our Gallery application to both refine the existing capabilities and to introduce new useful functionality; particularly for Albums.
We have clarified how to submit images directly to a category on the first step of the upload form in Gallery.

Clarification for submitting directly to a category
When submitting images to the Gallery, a simple "Add more images" button has been added to the wizard. While it has always been possible to add more images by dragging and dropping them on to the upload area, or by clicking the "Choose files" button again, the addition of this button should help add some clarity for users who overlooked these capabilities.

A new "Add more images" button makes adding additional images easier
Applying the same details to all of the images you are submitting has been made much simpler. When you begin entering the details for the first image, you can specify a template to use for the caption name leveraging a special replacement "%n". A small help icon next to the caption field label explains how to use this capability. When you are done supplying the details, you can click "Copy details to all images" and your submission will start instantly, using all of the details supplied for the image you are editing. You can quickly set tags, an image description and a caption name template (for instance "Aquarium %n") to all images using this new capability, useful when submitting 50+ images at once. Of course, you can still supply the details for each individual image as well, if you wish.

Submitting a lot of images at once has been made easier
In addition to improvements for submitting images, albums have been updated to include many new features, including:
Commenting Reviews Reactions Messages Featuring Hiding Locking Reporting Searching A new Gallery widget (sidebar block) to show albums anywhere throughout the Community Suite has been added as well.

Album overview page
Going along with these changes, we've improved how groups of images that are submitted to an album are handled in searches. If you submit multiple images to an album, you will only see the album listed in activity streams, and similarly if you follow a bunch of images in an album these are grouped as well, making activity streams more useful and easier to follow.

Activity streams have been updated as well
The changes to albums and image submissions will simplify your users' interaction with Gallery in 4.2, and make submitting images and new albums, and working with those albums more useful and robust.

This entry is about our IPS Community Suite 4.2 release
In IPS Community Suite 4.2 we have added a bunch of new settings for the Downloads Index Page.
 

Downloads Index Page - Settings
With 4.2 you'll be able to hide any of the boxes.

Another often requested feature was that people want to be able to choose the categories from where the files should be fetched
This way you'll be able to hide files from some very old categories.

Hidden Categories

There are many strategies for growing your community, such as newsletters, mailing lists and advertising on other sites.
IPS Community Suite 4.2 puts a new tool at your disposal: promotions.
There’s no denying the popularity of social media. Worldwide, Facebook has 1.86 billion users active monthly. Every day, millions of people are using Facebook to speak with friends, to talk about their interests and to find new people to connect with.
Of that 1.86 billion people, a good portion of those are actively discussing topics your forum covers. There is a huge opportunity to tap into social media to join in the discussion and to promote your community and provide a venue to carry on the discussion.
For a while, we’ve had social media log in extensions, which means that your users can sign into your community simply by clicking a relevant button. We’ve also had the ability to share things to a personal Facebook account. These tools are great for your users, but how do they help you, forum owner?
IPS Community Suite 4.2 introduces a way to promote your content directly to your brand’s Facebook page and your brand’s Twitter account.
You can curate fun and engaging topics and share them. The workflow is simple. Simply browse your community and queue up interesting topics, comments, gallery items, blog posts or database articles for posting throughout the day to your brand’s social media accounts. You choose the schedule, the hashtags and the wording to send.
Let’s look at the feature set in more detail.
Your first stop is to set up the feature from the admin panel. The system will guide you through the necessary steps of connecting your Facebook and Twitter accounts. Once Facebook has been set up, you can select any page that you are an administrator of on Facebook.
 

The admin panel also offers scheduling options and permissions.
 

You can pre-set the times for when content will be posted. Facebook and Twitter both have analytic tools to determine when your visitors are most frequently online. A good tip here is to set the time to a slightly odd number, so 11:45am is better than 12:00pm as you are likely to catch the attention of someone waiting for lunch, or a lunchtime meeting.
 

You have full control over who can promote items to your social media accounts. You can specify by group or pick individual members who may not be in those groups.
Now that you’ve set up the backend, we can get promoting.
Each item, that is a topic, gallery album, blog entry or article has its own Promote button.

 
Each post and comment can also be shared individually, which is an easy way to share great content your visitors add to existing conversations.

 
Clicking this brings up the sharer.

 
This is where you can customize the text that is sent out to each social media channel. You’ll also notice space to promote this item within your own community in addition (or instead of) Facebook or Twitter, we will explore that shortly.
The sharer is smart enough to pull attachments already added in the post, and you can upload your own images to be sent. Generally, shared items that have an image get better organic reach than just text alone so you’ll almost always want to choose or add an image. Twitter can use up to 4 images, and Facebook allows 1000 pictures per album, but you’ll never want to upload that many!

 
Once you’ve filled out your content and picked your images, you can schedule the promotion. Generally, you’ll want to use the auto schedule option as this allows you to just stack up multiple items and let the auto scheduler post the items according to your pre-set schedule. You can also set a specific date and time if you are looking to run a promotion or other time sensitive event.


The promoted content viewed in Facebook and Twitter
It’s easy to see the status of your queued and sent items from the moderator view.

 
This area allows you to see previous promotions and modify pending promotions.
Earlier, we mentioned that the system has the ability to promote content internally. Promoting items to your own community lets you, the community manager, curate interesting items and comments and present this to your community. This is a great way to allow your visitors to explore content you think they’d enjoy.

 
Promoting content to your community via Our Picks also allow you to promote content if you cannot or choose not to use social networks. It has the advantage that social networks do not have over a community platform like IPS Community Suite: consistency. The content on your community is always there whereas a social network is all about right here right now. Miss it and you miss out. On your community you can engage and re-engage a subject all you want. 
Of course, we’ve built a widget that you can drag and drop to most pages to make this curated list more visible.
IPS Community Suite 4.2 gives you, the site owner and community manager the tools you need to reach out and engage new users already discussing the topics on social media your community covers. With single click sign in and the built in retention functionality the suite offers, you’ll have a powerful way of growing your user base. It furthers that goal by created a list of that promoted content for continual reference and promotion for visitors already on your site.
We’ve got lots more to discuss on this subject, and in the coming months we’ll be putting together some guides on social media best practices and how to leverage Facebook’s excellent post promotion / pay per click tools to further boost your site’s visibility to social media users.
We’re here to help you make a success of your community and to give social media users a venue for when they outgrow Facebook.

This entry is about our IPS Community Suite 4.2 release.
We are happy to introduce the next major feature that will be available in IPS Community Suite 4.2 - Clubs.
Clubs are a brand new way of supporting sub-communities within your site. Many people have requested social group functionality in the past and Clubs are our implementation of this concept. Let's take a look at a few screenshots, and then go over what they are capable of doing.

The Club directory

A Club homepage

Club member listing

Example of content within a club (topics, in this case)
There's a lot to digest there! Let's go over the basic functionality.
 
Club Types
Four types of club are available:
Public clubs
Clubs that anyone can see and participate in without joining. Open club
Clubs that anyone can see and join. Closed club
Clubs that anyone can see in the directory, but joining must be approved by a Club Leader or Club Moderator. Non-club-members who view the club will only see the member list - not the recent activity or content areas. Private club
Clubs that do not show in public, and users must be invited by a Club Leader or Club Moderator As the site admin, you can of course configure which club types can be created and by whom. You could, for example, allow members to create public and open clubs, but allow a "VIP" group to also create Closed and Private clubs.

Admin configuration option for Club creations
 
Club Users
Each club has three levels of user:
Leader
A leader has all of the permissions of a moderator, and can add other moderators. They can also add content areas (see below). The club owner is automatically a leader. Moderators
Moderators, as the name implies, have the ability to moderate content posted within the club. As the site administrator, you can define which moderator tools can be used. You could, for example, prevent any content being deleted from clubs, but allow it to be hidden. Moderators can also remove members from a club. Users
Anyone else that joins the club.
Defining the moderator permissions available to club moderators
Your site administrator and moderators, with the appropriate permissions, are able to moderator content in any Club regardless of whether they are a member of it. 
Clubs can be created by any user who has permission. As you would expect, this is controlled by our regular permission settings.
For closed clubs, there's an approval process. Users can request to join and the request must be approved by a leader. Leaders get a notification when a user requests to join; the user gets a notification when their request is approved or denied.

Approving and declining join requests
 
Club Content
Club Leaders can add a variety of content areas to their club - forums, calendars, blogs and so on. It's important to note that these content areas are fully functional just as if they existed as a top-level admin created area. They will appear in search results, activity streams, users can follow them, embed links to them, and so on. If a user has permission to see a forum (for example) within a club it will behave exactly like other forums they see - and the same for all other kinds of content.
Each content area a leader adds can have a custom title, and will appear in the club navigation. This means, for example, that you can have multiple forums within a club, and give each a different name.

Adding content areas to a club
 
Club Custom Fields
Clubs also support custom fields. Custom fields are defined by the site administrator and can be filled in by Club Owners. The values they enter are shown (along with the club description) on the club homepage.

Custom fields in a club
On the Club Directory page, users can filter by the custom club fields.

Filtering clubs
 
Club Locations
Clubs have built-in support for Google Maps, allowing users to specify a physical location for their club. Let's say you run a community for car enthusiasts; each club might be tied to a particular region's meetup. The Club Owner specifies the location when setting up the club, and clubs are then shown on map on the directory page:

Club locations
And within a club, the location is shown too:

 
Club Display
We offer two ways to display club headers within the club - the standard way, shown in the screenshots you've seen up to this point, but we also have a sidebar option. This is something the admin sets globally for the site, rather than per-club. This is useful where your site design doesn't facilitate another horizontal banner taking up valuable screen real-estate; moving the club banner to the sidebar alleviates this pressure on vertical space.

Sidebar club style
Using Clubs in Other Ways
There's a lot of scope for using clubs beyond allowing users to create their own groups. You do not even have to call them "clubs" if that does not suit your use case. For example, on a company intranet you could rename Clubs to "Departments", and create a private group for each of your main roles. This would allow each department to have its own community, with its own forums, gallery, file sharing and so on, private and separate from other departments.
Similarly, they'd also work well in situations where you as the site admin want to create entire micro-communities. Take for example a video game publisher. Using Clubs, they could create a micro-community for each of their games, complete with forums, galleries and so forth, and then set the Clubs directory as their overall community homepage. Immediately, they have a setup that hasn't until now been possible out-of-the-box with IPS Community Suite.
 
We expect our clients will come up with some really innovative uses for the new Club functionality, and we can't wait to see what you do. We'd love to hear your feedback - let us know what you think in the comments.

This entry is about our IPS Community Suite 4.2 release.
IPS Community Suite has long had a reputation system; first we had a simple up/down system, later updated to introduce a Likes system as an alternative. Whichever system you chose to use, it tied in with our reputation system.
We're pleased to introduce the latest updates to the reputation system, and it's something that has been requested for quite some time: Reactions.
Quite simply, reactions allow users to offer more fine-grained sentiments towards content than a simple up/down or 'like'. They are now in common usage on social networks, and so users expect to be able to be more nuanced in their response to something they see.
Let's see how they work in a post, and then cover the options you'll have available.

What you see above is the default setup for a site that has used the Like system in version 4.1. We include 5 reactions by default:
Like Thanks Confused Sad Haha If you currently use the older style up/down reputation system, don't fret - you'll still get the new reactions on upgrade, but they'll be disabled by default and instead the new reaction UI will show up/down reactions. This gives you the flexibility to decide which of the new reactions, if any, you want to allow.
So, those are the basics - but what configuration options can you expect to see? First, you can of course add your own reactions! We expect that beyond the default reactions you'd expect to find, some sites will want reaction types specific to their use-case. On an intranet, you might want to have 'agree' and 'disagree' reactions for staff to use when responding to discussions. On a gaming community, you might replace the icons to be some graphic from a video game that means something to your particular userbase. There's a wealth of possibilities.
Each reaction you set up can be configured to adjust the original author's reputation count - a reaction can be positive (i.e. award a reputation point), negative (i.e. subtract a reputation point), or neutral (i.e. leave the reputation count unchanged). Our default set won't include any negative reactions, but you are free to configure these and new reactions to suit your own use-case. A user's total reputation count is still shown alongside their content and in their profile, of course.
If you don't want to use the new reactions for whatever reason, you can disable all of them except Like, and it'll behave just the like 4.1-and-earlier system:

 
Sites that currently use the up/down system don't show a list of names of users, and instead show an overall reputation score for the content. With the new reaction system, you can enable this even if you don't use up/down reactions. This is great if you plan to use reactions as, for example, an agree/disagree system, or where the content score is more important to your site than the individual reaction types.

How the reaction UI looks with the 'count only' setting enabled
As you'd expect, you can click individual reaction counts (or the overall reputation score, if you enable that setting) to view who reacted to the content. This remains a permission setting that you can apply per-group.

On touch devices, on-hover functionality is not suitable, and so for these devices the reactions UI looks like this:

Reactions play well with all areas of the suite, including Recommended Replies:

...and activity streams...

...and a couple of places we aren't quite ready to reveal yet  
 
We hope you're looking forward to this new feature as much as we are. It's already been a hit on our internal testing site, and we're looking forward to seeing how clients customize it for use on their own community.
