Also I do not like the idea to have a resign option. Take an example someone else posted a couple of weeks ago.
If someone has 0 points left, and you see this and bet 1 point - but they decided to resign instead of playing their bet of 0 - then that just messed up the game for the many players who just bet 1.
Also another example is when there are few players left - I know for myself, I bet differently depending on how many people are left in the game. If people just start resigining 1/2 way through the game, it could mess up bets for users who like to use a little bit of strategy when placing bets.
Anyway, I really don't see this becoming a big problem after this game has been around for awhile (and after the very big first one).
