Requesting to be made the administrator of a Facebook page isn't necessarily difficult, although it depends on the current administrators of said page or group. When you compose your message you should be clear and succinct; you don't want to bore your audience. You should provide reasons as to why you want to be an administrator and give a few of the ideas you'd like to implement. Do not elaborate; a sentence for each idea should suffice. If the administrator wants details he or she will ask.
Log in to your Facebook account.
Navigate to the page for which you wish to become an administrator. Look for the "Admins" heading; these are the people you need to contact in order to become an administrator.
Click the name of one of the administrators, then click the "Message" button. Compose your message.
Click the "Reply" button when finished.
