CoolTools: TeamSnap is an amazing tool for organizing a sports team, club, or other function where you have to coordinate groups of people. There’s a free version that’s got a lot of features, but even more are available on the deluxe version which is about $75 per year. We’ve been using it for about 4 years for different sports (soccer and baseball) for my two boys.
It enables me to manage my teams with ease, both remotely when we’re traveling through a smart phone, as well as using my desktop computer. It’s easier to use than competitor sites that I’ve seen and makes it very easy to coordinate your group of people. Even users that aren’t very computer savvy have been able to use this product very easily.
The free version let’s you manage your team and push the calendar to an iCal that can be accessed and automatically synchronized to a BlackBerry, Android, iPhone, iPod Touch, a Mac, or a computer using the more recent version of Exchange. You can also e-mail your entire team very easily.
