Starting around the spring of 2001 the site's focus shifted to the forums.  I started with UBB Lite, then went to UBB Classic 5, then vBulletin 1, then vBulletin 2, vBulletin 3, etc.  The forums took on many different styles over the years.  These are HTML snapshots of different vBulletin styles that I have used.  I made all of them myself except for the OS X style which I purchased from a guy by the name of Sinecure over at http://www.pixeljunction.com/
