The header is just way too big. I'm running 1900x1200 and I have to scroll down almost 4 full pages before your actual forum even starts.

Thoughts:

- Ditch the doubled up Adsense. It's already above the Navbar, you don't need it IN the navbar as well. (Personally I'd just leave the Navbar adsense in and dump the big ad unit above.)

- Move the Statistics box to the bottom. Top XX stats are cool, but they aren't more important than the actual forum itself.

- Statusicons are too big, and they don't align properly. For example, the statusicon for the "Crews/Hook Ups." forum is indented in about ~10px from the audio forum above it.

I like the color scheme, but I think a subtle dark tiled background would look nicer than plain old black. Nice site in all, but the massive headers just kill it for me.
