I have posted the suggestions which make sense to my tracker http://addons.invisionzone.com/projects/project/16-referrerrs/?do=issues
 
Why would you want to turn this off and where else would somebody set the referrer? This application wouldn't make any sense without the referrer field.

Can do this?
select allowed groups to use this mod, or/and admin can allow specific members to use it On/off required inviter name upon registration list of all invited users in ACP with filter option for search invited members for specific user promotion to the new group after reaching specific amount of referred users (automatically and manually) ability to check all referred users via ACP ( member manage ), ability to add/edit/remove referred transactions, ability to turn off the "Referrer Information" block in profiles, ACP permissions (manage: add, remove, edit) Tell us the current feature list.
Thanks
 

sounds like a pretty popular request though.

Long story short: location was added when the app was already in an advanced stage of the development and the way IPS built the GeoLocation stuff, a complete rewrite of the entire category stuff (script and templates) was required, so not to further delay the release, which was already quite late, decided to leave this for a further version, probably in 4.2.
Well, that's not the main porpose of this app. Change the text is easy, since the app is fully translateable... but I'm not sure if it will fit your needs in that manner.

Since installing this, and vehemently advertising its features to my users, I'm yet to get a single person to actually register from invitations... while countless have found us through other means.
Email isn't the best solution for this. Please consider adding referral link functionality to this plugin, or even as a separate addon to this plugin which costs money on its own. Gamers and many other niches don't actively use email. They use Skype, Steam, and other social platforms like that. Having a referral link users can generate to invite others would make this hook so much more worth it.

Having tabs in the user menu for each "sort" option seems awkward. Users will need some kind of sort tool if this plugin is going to be a robust member list.
Can have location, post count etc plus custom profile fields.
Here are some examples of member search.  (and member browse)

You either posting in the wrong support topic, or this app doesn't function the way you think.
The members location will not be presented without their consent, meaning they would have to add them selves to the map using the "Add Location" button above the map. And it will not be limited by who's online and who's not. See this site for a real world example. 
And entering an API key from Google is no good. That will not work. Read the description on that setting again to see where you get your API key from.
Could you send me the URL to your site? Think the CSS for the map is missing. Going to ACP > Support and tick "Something isn't working correctly" should rebuild the theme caches.
