BigBoyDan claimed he invented it. Funny though I don't recall any of them being around when we went through the logic scenarios and programming, planning, investment modeling leading to the full concept layout.
The points sytem as we know it today was an offshoot of the short lived poster rating, the already planned
store and Bill's idea for a peer to peer concept,
a concept where guys would challenge guys to single bets and heads up contest. From there the team kept advancing the concept and suggested the suite of games and poker. Later the Pro program and trivia were developed.
is the intial idea was Bill's and it was far less in scope. The concept as we know it
today was a massive organizational effort with great feedback from the community.
