A very enjoyable format in which players contact opponents from the league, set up a match , play and report the scores back to me! I then use a somewhat meticulous scoring system to rank each player and the results - much like a baseball batting average.
Ya'll check out everything about it (and the League Message Board) at The Breakers Challenge League and see what you think!
Started in the fall of 2010 - the Breakers League is an on-going system. Cost is only $5 for an entire whole year mostly to maintain the web-site and administration of the system itself!
