Google Mail and Calendar

I was going to sign-up with Training Peaks Coaching Software but decided not to. After all, why do I need it? Why pay a one time $90 coaching fee, and charging my athletes over $100/yr. to send Training Plans over the internet? Yeah, I know most USA Cycling coaches use Training Peaks Software, but I can do everything with Google Mail and Google Calendar- for FREE. http://www.google.com/ If you don't have Google Mail or Calendar..sign up now!
