Yes, there have been a number of threads created on this subject, but lately it seems to have really ramped up. I just had a Nation member hosting a front 9 Congressional multiplayer stroke game quit because everybody was taking too long on their shots. He's the one who set the game at 90 seconds. (the fact that he was +5 on the 4th hole may have had something to do with it, but hey)
It's really time for WGT to do something to punish quitters. Loss of XP comes to mind; too much & a player could also lose tier. Nation members who get below about 60% should temporarily lose their pennant, until they get it back over the 60%-mark.
