My challenge has been in collaborating with shared calendars. In iCal I have 9 calendars that all overlay. Each calendar is for a different item (business, health and fitness, fun time, contribution etc.). I want to have the ability to work with a dedicated personal assistant and have her enter meetings for me.
With iCal, I can share a calendar and she can subscribe, but she doesn't have edit privileges. If I sync my computer with hers using Mobile Me, she has access to all my calendars, e-mail, contacts etc. and some of this is private.
1) Sharing Multiple calendars
2) Maintaining privacy for some appointments
Any ideas here? Cheers!
