I've often found that I'll do something in the forums here, and then want to go back to the main site. As a simple thing to add, could we put a link back to the main site?
Maybe somewhere in the bar that says: [Home] [Help] [Search] [Profile] [My Messages] [Calendar] [Members] [Logout]
Would that be asking too much? I honestly think it's a swell idea. (Although very low-priority)
