There was at least one more that was hosted that Kyle and (I believe) Frank made it to, which if memory serves was around 2006, which I was unable to make.
Met LanceHarbour, McSweeney, JackDaniels, JimmyinTx, Bluffton, ndfredo, wrdomer, wrdomerson, DirtySanchez, and a few others. They were a great time.
It's worth mentioning that the Football Board was quite a bit more active than the Open Forum at the time.
