To learn how permission groups work, see Utilities: Administration: Administrators: Permission Groups.
Once you have created a new permission group, you will be taken to the Utilities: Administration: Administrators: Permission Groups main page. From this page, you may select the permission group you have created and add, edit or delete permission rules for it.
Permission Group Name
Enter a name for the new permission group. This can include any alphanumeric characters, including spaces, and can be up to 50 characters in length.
Description
Enter a relevant description for the permission group. This can include any alphanumeric characters, including spaces, and can be up to 100 characters in length. Make sure the description is helpful in your understanding of what this permission group will allow and disallow. For instance, "users are blocked from the server administration page".
