I bought the name gamerforums.net yesterday and am developing it into a forum. I have just launched it am looking for critique on its design. http://www.gamerforums.net/
Too many empty forums. I would suggest removing some forums and add more later. Design looks nice for me.
I like the design and colors, even if it's not unique. Like andriusk said, there are a lot of empty forums, but you're just starting out. You don't have too many forums, and I don't think any should be removed. Otherwise there's not much else to say. It looks nice, now it just needs activity.
In general, the layout is decent. For a gaming site, I'm not sure if the color scheme suits the theme at all. Maybe try replacing the white and orange with dark green or red instead.
Looks fine...and I'm sure you'll tweak it as you go along, but as with any forum, people talking is the key...so now you just need some traffic.
