I like your logo and thats all. As AsianKid said your colors are very dark. I also dislike your type size. I think that you spent about 10-15 for this site.
You should redesign it.
Dark is good, as it fits the forum topic... But it maybe a little to dark. In a way, it's kind of hard reading threads on the forum, IMO. I would try adding a few borders and/or bars to kind of seperate the content so it will be easier to navigate.
the color scheme fits well with the site imo, the navigation is nice and the actual header is cool, however, the layout is messed up, i'm using a 19' monitor with high res and nothing seems to fit, the header image is in between the nav and forum content and the forum content areas go out to the far right past the header image because the image isn't as large
