I'm a relative newbie compared to the old guard around here. I found Coach Roy's old predecessor board to Wildcat Report and started posting during the 2000 season (although it might have been late '99). The "Joined date" of May 29, 2001, that many of us seem to share, is a total misnomer, and is probably related to some sort of Rivals database reconciliation.
Some other long timers are Hoosboot and IdahoCat, although I haven't seen the latter in awhile.
You might remember that the old Rivals was going broke and out of business in 2001. Then some new financial backers appeared and saved it. So anyone who was a registered member at the time, like you, me and ECat, shows a joined date of 5/29/2001. If you notice, there are a whole bunch of people with that same start date.
