I want to create a calendar, where multiple users can add and modify their own entries, but not entries of other users.
I created a group where I included the users and gave write permissions on the calendar to that group.
Now everyone in that group can modify every entry. How can I permit only modifiying own entries?
And: is there a way to display the owner of each appointment in the overview? Then I could use this as a kind of holyday-planner.
