If possible could someone shed some light on how to insert custom HTML in to spaces on the forum.  IE: in this image below I'd like to put some custom HTML where the arrow is, both on the Forum Home and Topic Index in the sidebar.  

I've also found in PAGES that I can create custom HTML blocks, and call those blocks using {block="my_block_key"}, is it possible to call those to parts of the forum?

Create a page like:

Details- "Use suite HTML wrapper - No" ;"Page Wrapper- Custom Wrapper"

Content- Your HTML code.

Create a Custom block

with content:

<iframe style="display:block" src="http://your adress/your page.html" frameborder=0 height='xx' width='yy'></iframe>

In the page of your site where you want, use "Manage Blocks-Pages".

Drag and place in which field you want the widget to your new block.

Hi @Adlago your suggestion works perfectly for those pages that are within pages, I am trying to insert a custom block or code in to the Forum which is not possible using the above method.

Says who? 

I don’t see an option to add a WYSIWYG editor block in the forum, but custom blocks do work. 

Hi @opentype perhaps we are looking at different things here?

How is it that you achieve custom HTML blocks on the Forum Home and Forum Index pages?  
I can not find a way to place the custom blocks in to those spaces.

​Just drag & drop the Custom Blocks widget and then click Edit to choose the custom block you have set up. 

Houston we have a problem...  Seems like I'm not being presented with the Custom Blocks option you have in your AdminCP @opentype .

How did you make it list 3 posts under the forum title?

Is that an option or an edit.?

@K4RL custom edit, paid a developer here to create it for us as we currently run this on our phpBB since 2009 which we will be migrating to IPS4.

Ahh that's pretty kewl I really do like that touch
