Accel V6 (It's a car site, if you hadn't already guessed)

[Jon.]

Right, so I've just redesigned my site and I'd like some critique as to what's hot and what's not, basically. I've got the opinions of most of my members so far, and all has been positive, but I'm always open to suggestions (hence this thread). Or just that you like the design - I'm happy to hear that after months of development too.

Description:
I started running my site (on vBulletin atleast) about a year and a half ago. This is now my 6th design for the site (V6). Accel is a forum dedicated to cars and car chat, basically.

Known bugs:

• Header isn't transparent in IE 6 or below
• The speedometer clock isn't transparent in Firefoc for Linux

Thanks

Jon
