The Administrators page is where you can create Admins that can login to the backend and administer your portal.
Clicking on this link displays all your current administrators
On this list you can see the 'Roles' that are assigned to this user. An admin can have multiple roles assigned. The role an admin has determines the restrictions he might have on the portal.
To create a new Admin, click on the 'Add New' button
Enter the details for the user. Specify the roles
from the dropdown that you would want the user to have. Click on Create
when done.
