Skin looks good, but I can't stand adsense at the top of the page. Just clutters things up and makes it look like the admin is greedy.

Nothing personal, site looks great otherwise. It's just that I'm running 1600x1200 and even with that resolution, your actual forums don't start until almost 3/4 of the way down my screen.

I'd also use some kind of darker, even slightly darker background image for the areas outside of your forums. It'd make it easier on the eyes and add texture. Also, drop that "Skin by Extremepixels" tag from the bottom right, or at least make it look a little less... like more advertising.

I've never been a fan of EP skins, they all look so generic. :\
