Calendar for a sportsclub - how to do that ?

Hi there,

For a client I need a calendar for using the different sportfields and courts. There will be 7-10 Groups who need to make a plan who is using which field at what time, day and week. Im not sure if everbody is allowed to see, but only this groups should change dates.
My first impulse was using google calendar, but Im wondering if there are other solutions. Maybe someone has experience with and can give me a hint?
I guess one of my problems right now is I dont know a english Phrase to describe my objective. In German it would be
"Belegungsplan" (Plan to reserve) but with my poor translation ;-) I cant find any jquery or whatever.

Thanks
PS: Project will be my first shoot with Revolution

You could try: http://rtfm.modx.com/extras/revo/mxcalendar however I havent used it myself - never had the opportunity, that could suit your needs.
