A Super Administrator has full control and can manage the users assigned as Administrator and the access to such tasks as seeing events, donations, news and more.
User permissions can be found with the "Permissions" tab when viewing a user (Admin Area > Users > View Profile). Under the "Administrator Settings", select the role you'd like to give this user from the Administrator Rights menu. You'll then be able to toggle each of the tasks (areas of the Admin Area) that you'd like to give this user access to. Use the Select All toggle, to conveniently toggle all items.
Once you have done, scroll down and click Save Permissions.
