Deleting Facebook Group
1. Log in to Facebook and see your group that you wish to remove.
2. Click the "See All" link in the Participants section on the appropriate side. A list of every group member appears.
3. Click the "X" beside a team member's name as well as click "Eliminate." Repeat this action up until you are the last group participant continuing to be. After deleting all members, Facebook reroutes you to the group's account page.
4. Click the "Leave as well as Erase this Team" link.
5. Click "Erase Group."
Idea
You have to be the team's designer to deactivate the team. If the creator left the team, after that just a team manager can erase the team.
