My thoughts on your site
I know you're obviously on Microsoft hardware from the .aspx extensions but even the free PHP based forum phpBB 3 is 10x better than this?
Plus when I login to the site it doesn't log me into the forum? I have to login again.
This message reply box works bizarrely in FF3, it defaults to putting a single space at the beginning of a new paragraph for some reason.
Finally, from a web development perspective, you shouldn't be using a Transitional doctype, the site doesn't even validate with a Transitional doctype which is one of the easiest things to do. I understand you're probably using some sort of CMS but in this day and age, building a new website like this is something I'd be embarassed to do as a web developer....well I actually couldn't build a website like this any more.
