Purple: GST (Grooves Speed Team) was an online checkers team from 1999-2003. The leader was Favian Elmore (gst_favian) and consisted of very good online players, a few mediocre tournament players, and a few program players. These players played at IYT, Kurnik checkers and Yahoo! checkers. The team is dead now - I haven't seen a player with the gst subname in 2 years or more...

There are many checkers teams in kurnik checkers, and maybe some in yahoo checkers. These players don't play in BK or IYT. They are highly skilled speed players.
