I have the following hierachy: school class 1 student 1 student 1 content student 2 content etc. student 2 student 3 etc. class 2 class 3 etc. And basically there is three different typs of users: Administrators Teachers Students My problem is that I want to give each student the right to edit the content in their own folder. Their folder is a zClass that subclasses objectmanager, and they can only add certain other classes. Now how do I best set out to do that? It should also be easy for the teacher to administer his students. The options I can see: - Make an acl_users folder in each student folder, and give the student the admin role in that folder. That would work but seems a bit longwinded. - Make a student an owner of a folder? (I am not really shure what consequences that would have) Regards Max M
