Login Page

So I've forgotten where the file is to control what shows up to the right of the login box. Picture explains what I'm talking about: http://img859.imageshack.us/i/captures.jpg/ It's the blue area.

It used to show recent updates, but it's a private site (requires invite and login) so the other admins wanted me to stop it from updating the contents so people wouldn't see member's profile photos and what not. Now they want me to put "samples" of site content to attract people and show we have something to offer. I want to use this area, use jquery to show a hidden div and use that for the content. Anyways, where is the file that controls this area? I have riverdashboard and nothing else which should be affecting this region.

 

So, what file controls this area? It's the standard one col/left side view.
