Getting there!

Your rank images are broken currently though. Nice clean skin, I'd darken the background color juuust a little bit so that the actual forum tables pop a bit more.
The only other thing I can offer as a suggestion is to trim down the number of forums until you have a solid base amount of posts. 5-8 forums with a lot of posts in them is much more appealing to potential members than 20+ forums with only a few. I'd combine a few forums for starters and start branching out once you get a solid memberbase.
