Adding Administrators
You can add administrators to your site. Once added, the administrator will receive an email (at the email address you specified when creating an account) with full instructions on how to log in. Once they log in, they will have full administrative access to your site.
Step-by-step Guide
Go to Site Administration > Users > Accounts > Add an Administrator.
Enter the administrator's email address as well as their first / last name.
The email address must be unique.
Click on the "Create user" button at the bottom of the page.
