I am insecure about the design of my forum, I can't really decide whether I like it or not. (Beware, the layout is pretty simple/plain, I tend to dislike clutter).
The forum itself is good, I like the plain easy-to-read layout. I'd work more on the logo/header. Can't quite put my finger on what looks wrong about it, sorry that I can't offer really 'constructive' critique of it.
