I do not know if I installed correctly but does not work the permission settings.
I set the permissions in both categories as ACL users.
I created three groups (besides the super user):
Visitor: No permission
Joined: Create questions
Author: Create responses, can not edit, delete and acts as moderator
Super user: All
If I agree to a user folder, I can delete, edit, but I could not assign or moderate
Not even with superuser I can assign or moderate, although other functions.
What have I configured wrong?
