Hi, A question: How do you share a group calendar properly using multiple calendar clients? For example, I have two user's A and B in the same large group. A uses my web application to add an entry into the group calendar and appears as the Organizer. B uses some other client to access the group calendar and simply modifies that same entry without restraint. A is unaware that B may have maliciously changed the entry and other group members believe the modified entry belongs to A. I've thought of making the group calendar readonly for group members and using the admin user to create/update/destroy entries through my web application on the user's behalf, but there must be a better way. Plus I don't know how to modify the group ACL yet either. So that question again: How should I enforce ownership of group entries across multiple clients? - Tyler Keating
