online chess database for a team

I have recently taken over as coach a chess team. After a few tournaments I have realized the most efficient way to help the kids get better would be if ideally I could find the following:

An online forum where my kids (or I) could upload their game notation. It would go into a database (private would be preferable,) where I could see, make comments, etc... I don't have much of a budget from the school, but would be willing to pay out of my pocket to get this started. Any suggestions would be appreciated.

Thanks 

Hi, you could check out 365chess.com .  I know it has a feature to upload your own games into a private DB, but I've never used it though.  Anyway, its free to sign up and it's at least something to play around with.  Good luck!

Thanks Justin, I came across it in my brief internet search, I have not signed up, will check it out!
