Your right its mainly masters and above that quit but i see no reason for them doing it now I got so pi**ed with quitter I started my own country club and the only rule I put in place was 3 quits against another member your out simple.I have 42 members join up in first week and had some great games even a 4 some 18 hole and we all finished!!! Not had one complaint yet about someone quitting
this is the link to the club home page

My idea behind it is to get 250 members and only put members on my friends list that way i know i will get a full game 99% of the time I say 99% because some do have connection problems.
