Nice job with the header graphic, did you use photoshop? I like the blue-orange color combination on your pages but you should put the ad banner at the bottom of the content, not above it. I would remove the "Last 10 Topic" box and be careful about openly putting your e-mail address on a page (could attract spammers). Lastly, I would make the forum skin match the blue-white-orange scheme of your other pages so that it looks like the same site, because you've got a great one here!
