I like it, but something about it is just too busy. I think if you stretched your table out another ~80 pixels or so, it wouldn't bunch up the forum description text quite so much.

One other thing, just personal preference, is that I'd darken the background color just a tad. The whole forum's bright, and if the background was a tad darker it'd be much easier on the eyes.

Nice and clean layout though, very nice work.
