This is a nice clean design, even though I'm not usually in favor of paragraphs that span the entire width of the screen (stretching tables). Good, very simple navigation, and you've remembered to include plain text links at the bottom of the page. Any possible design suggestions (like making the most important links more prominent than those of lesser importance) would be nitpicking.
You do, however, still have some pretty serious cross-browser issues, and it's not difficult to see the site was designed for and using IE. Some of the issues degrade gracefully, such as the hover links and the watermark background, but some don't. The center column of the top table, for example, looks good when you first enter with Netscape; but if you scroll down and then back up, Netscape gets very confused and it looks a bit like pickup sticks on steroids. You also have a graphic in the lower left corner, for downloading IE, that consistently comes up as a broken image in Netscape. Not sure why, though I suspect it's the space in the filename. (Because of the differences in operating systems, it's traditional to use the lowest common denominator when naming disk files - everything in lowercase and NEVER use a space. That has more to do with your server than the clients, and if you ever move to a non-Unix machine you'll be glad you did, but in this case it appears to be affecting Netscape, too. I suspect it's the URL encoding and NS isn't properly converting the space char to a %20, but that's just a guess.)
It's obvious the content is still growing, and in time you'll want to add more interactivity (like a search feature), but that should be a walk in the park with such a well designed foundation.
