Okay - after Matt kindly pointed out that none of us were born designers, I think I chip in with a proper review this time (minus sarcastic comments).
Only one off-topic remark: anybody else who doesn't like the waybackengine as it faithfully records that awful table-based, frame-layout blinking site design which was done years ago & should rightfully be buried never to be seen again? I just got reminded today and just hope none of customers uses it to look up our old designs.
Okay, but now to the site review:
1. Fixed box height for the main content: Not necessarily a negative element but I'd like a robust reason why this was chosen. For customers who spent good money on nice large screens it's a bit of a nuisance having to scroll when there's so much empty white space left below the box.
Also try increasing the font size (both FF and IE7 alllow this with CTRL +) ... text starts overspilling. For CSS compliant browsers it's better to use the minimum height command, but then a hack would be needed to give it a fixed height in non-compliant IE versions.
2. The tabs at the top - look at first glance like the standard tabs but don't behave like them (no change to indicate which section you are in). Normally I'd expect tabs to behave like this:

3. A personal comment - the best advice I ever saw with regards to design is "be bold". How that's implemented can differ from site but I usually see whether I can create impact with a big heading, a bold image, a striking colour choice .. good sites usually have some really bold design statements. NB: not saying I'm achieving this, but I'm striving.
4. If your bookshelf still has space I recommend
Bulletproof Design - it's a really good book and also explains why fixed heights usually are not a good idea. Also contains a really good guide to sliding backgrounds (bit like sliding doors but for divs) and is seriously easy reading with hands-on examples.
all the best - Edith
