As a group creator or group admin, you can promote, suspend, and remove members who have joined. You can promote group members to administrators to help you manage the group. Select “Manage Members” from the Group Options drop-down menu on your group’s homepage to manage the members of your group.
To promote a member to administrator status, locate the group member you’d like to promote to administrator status and check the box next to their name. Select “Promote to Administrator” from the Select an Action drop-down menu and you’re all set!
You can also undo this action by checking the box next to their name and selecting the “Demote from Administrator” option from the Select an Action menu.
To suspend a member, locate the member you’d like to suspend from your group, check the box next to his or her name, and select “Suspend from Group” from the Actions drop-down menu. You’ll also have the option to fully remove members from your group by choosing the “Remove from Group” option in this same menu.
