Changing the "What's Going On" box header color?

[RagingPenguin]

I'm sorry, but I can't seem to locate the class for changing the grey gradient in the header of the WGO box on FORUMHOME. I am using FireFox / FireBug, but still can't quite seem to zero in on it. What stylevar do I need to edit? Thanks!

It's using "tcat", but you can change it to anything you want..
