hi,
Hate quitters as much as the next player, was playing blitz at Congressional "random 2", when the third player in the group "holed out" his tee shot on the first hole (10th - par 3). Made a change for all the players to continue and complete the game (thanks to all we still had a laugh, with plenty of shots within1ft of the hole/flag that could have changed the game).
There is no point quitting in a Blitz game.
Blitz will allow you to continue to the end of the game, if you are the last player - just no additional XP.
Not sure how they'll track quitters, really hate the one's that create the game and then don't stick with it.
