To specify what the members of the new user group can see and do, we'll first specify which viewing access level this user group has. As stated before, this level defines what users can access and see on the site, but it doesn't give them the rights to do anything.
In this case, we want the new user group to be able to access the backend. For this, we can use an existing viewing access level: the Special level. In the default Joomla setup, anyone with the Special level can access the backend controls:
Go to Users | Access Levels. The existing Viewing Access Levels are visible, as shown in the following screenshot:
To add the new user group to the Special access level, click on Special. Add the new Contact Administrator user group to this level by clicking on the select box to the left of the name Contact Administrator, as shown in the following screenshot:
Make sure that your changes are saved.
