Have a look if you could, please.

I think I've got most of the issues ironed out with my forums, but input from others would be most appreciated.  I've checked out how it looks in Firefox and IE6, but I'm not sure how it looks in Safari, Opera, or on a Mac. Here's the url: http://masterquan.com/forums.

I know I've got a bunch of non-compliant code wandering around, but getting the code up to spec has been low on my list of priorities.

Thanks in advance for any feedback.
