Your forums look really good. The colors are flowing, the logo matches, the icons work with the colors, and much more.
There are some things I don't like. I don't like that with the current time on the front page, on the right where the main buttons line are is at the bottom and there is a BIG space above it. Also on the main page, there is some black lettering that says you aren't logged in. Doesn't look to good either. Maybe if you centered it.
Otherwise good job!
