User Groups allow you to more easily apply permissions to a group of users.
Create a group with the “plus” icon to the lower-right.
Once you have named the group, you can apply several options:
Auto Apply - This automatically adds new users to this group.
Site - This determines which sub-site the group applies to.
Site Editor - This will allow the user to see the Edit Mode menu.
Administrator Console - This will allow the user to see the Administration menu.
The options on the right are the same as for individual users. Any user in the group will have the selected options.
