I've been trying to solve this theming issue all day - I figured I'd come ask the gracious experts. (And be on the way myself to becoming such a good helper.)
I am trying to make http://devio.us/forums look like http://devio.us obviously.
The problem is, my top gray background is disappearing unless I remove
<!-- forum_head -->
from main.tpl
Any ideas on how to edit forum_head so that my background is displayed? 
Then I'm off to figuring out why everything has moved to the left.
Many thanks in advance,
Kayla
P.S. I realize that the link to PunBB is gone, this has happened in my madness. I'll be adding it back once this all makes sense.
