I have no huge issues with whatever AVS wants their site to look like. That having been said, I'm using retro right now just because I'm a creature of habit. Anyways one minor thing to point out - it could just be my browsers or something (Firefox, Camino, Safari, Webkit all on a Mac) but when I switch to retro I still see the second set of tabs as white. For example, "AV Science Store" through "Advertise" all go dark, but "Home" through "Logout" all remain white.
I've made sure that I don't have old stylesheets or images stuck in my caches anywhere, so I'm guessing this is just a peculiarity or limitation in the styling system for the forum software - but in case nobody'd noted it I'm just pointing it out.
Congratulations on the superb job all around you guys. I've worked in professional web design/development since its inception in the mid-90s and I know what a bear this sort of thing can be. You did an amazing job coming back up in only a few hours and even honoring old login cookies! I was amazed by that.
