If you enjoy playing frequent alt-shot without the hassle of quitters, consider joining a site that promotes a great atmosphere for that: http://www.wgtls.co.uk/forums/main.php
wgtls (WGT Ladder System) uses WGT for actual game play, but all matches are arranged at their site in the Meet & Greet chatroom. Once you're registered there, you can look for a Guild (club) to join, by announcing your availability in the Guilds Open Forum. Although there are occasionally pick-up alt-shot matches for fun, 99% of the alt-shot matches are between Guilds for bragging rights in the guild rankings.
For those players who want to go it alone, most of the other types of of WGT play also have ranking ladders at wgtls: blitz, 3, 9 or 18 hole stroke play, Blitz, 9 hole Match play, and numerous tourneys.
