TencapTennis.com graciously offered to let us run our flex leagues on their awesome website for no charge! I've updated the league info at www.MyRacquetDoctor.com/flex-leagues with details on how to complete your registration. I believe all your questions will be addressed there but if not please feel free to contact me.
PS~ Tencap also committed to providing prizes to the division winners if we can fill them with participants so please tell all of your friends!
