I like it. There's two things that I'd like to see changed however;

When I enter the forums section, it needs to get skinned out with colors - although the blue makes it pop off the page, so maybe that was the intent.

The header needs to shrink down when you enter the forum, otherwise it leaves for a LOT of scrolling when going through threads. One alternative to that would be to widen the forums after entering or something. It'll throw off the themed background a little maybe, but would be easier to read through and comment on posts.

Bipolar is something many people may be interested in, so don't be afraid to put in a Facebook link too. Maybe on the bottom right under the ABOUT section, add in a Facebook graphic so users can link up on Facebook too.
