You can easily add JPanel administrative users by going into the DonorShops administrative interface and clicking on Administration > Users & Permissions and then selecting the Add User button.
If you do not see this menu item, it means that your account does not have permission to add users.
When you create a new user, they will use the Email and Password value you entered to log in. You must ALSO click the Option check box to identify them as a JPanel User and then select the desired JPanel User option checkboxes.
Note: Only users who have the 'Can manage admin' option checked will be able to add additional JPanel administrative users.
