IE 5.5
1024*
NT dial up
took a while to load.
The nav is pretty cool. I like it.
I would fill the screen up a bit more. Lots of empty space floating around out there.
other then that I really liked the site. I found no ill errors in any code that I could see. unless you count the irritating MM everywhere

I don't think I would do your image loading in the body tag like that though.
ie
<body onload="MM_preloadImages('images/interface/upperleft/po.gif','images/interface/upper
right/portfolio.gif','images/interface/upperleft/dl.gif','im
ages/interface/upperright/download.gif','images/interface/up
perleft/pr.gif','images/interface/upperright/profile.gif','i
mages/interface/upperleft/co.gif','images/interface/upperrig
ht/connect.gif','images/interface/upperright/yah.gif','image
s/interface/upperright/yahpg.gif')">
as MM is doing that for you I suppose you prob. want to leave it I dare to learn more
