I have a member group that has very fine grain options when they log in. They should only be able to add, edit, and delete their own entries in a single channel. At the moment they can select any user as the author. Is it possible to not allow them to change the author?
You can currently to this by granting "Edit Entries", "Create Entries", "Publish Live Changes" and "Delete Entries" permission to a user.
However, none of those affect what shows up in the "Authors" drop down and I'm not sure they should. Technically, changing the author of an entry is still editing the entry.
Maybe what's needed here is an additional permission under "Edit Entries" called "Change Entry Author".
