How to Add an Administrator to Facebook
You can use Facebook events to announce parties and other social occasions. Administrators (admins) assigned to events set up in Facebook have the ability to invite additional guests and change event details such as the location and timing of the event. You can assign any of the guests as an administrator, but they must first confirm their own attendance at the event.
Log into Facebook using your user name and password.
Click the event to which you wish to add an administrator. Facebook shows all events in the "Upcoming Events" section on the right side of the Facebook homepage.
Click the blue "see all" link at the top of the guest list on the left side of the event details.
Click the "Make Admin" button to the right of the name of the attendee you wish to make an administrator of the event.
Click the blue "Close" button to close the guest list.
Tips & Warnings
- You must be the creator of the event or an existing administrator to appoint other guests as administrators.
