online tennis team management - TennisPoint.com
Not sure if you have heard of TennisPoint.com (http://www.TennisPoint.com), but if you play Flex leagues (T2Tennis, KSwiss, etc) or are a captain to a USTA team then you need to check out TennisPoint. Heck it is even free to register right now.
Tennis team management: netlineup.com
For those who are looking for a web-based tool to manage your tennis team with USTA, Flex league or ALTA, I recommend netlineup.com (http://www.netlineup.com), it's the most complete solution I have found on the market and I did spend a lot of time trying all the websites that exist. Setting up the team takes about 5 minutes and then all your communication and player tracking, etc. goes through the team website. Your players feel more involved, etc. Iíve used their system for a Junior team (USTA) as well as an adult team (ALTA), it works just great.
