I know Burgomaster- (or 'Miester'" ) as he's known now, has been her since 2005.
Actually, I've been here a little longer than that. Before my Burgomaster profile, I was registered here under another account (I think I just used my real name "Joe"). I think I forgot that I already had an account and registered again as The Burgomaster. So I've probably been here since around 2003 - 2004 or so?
