How To Remove A Group From Facebook
1. Log in to Facebook and see your team that you intend to delete.
2. Click the "See All" web link in the Participants section on the right side. A list of every team member shows up.
3. Click the "X" beside a group participant's name and also click "Eliminate." Repeat this activity till you are the last group member remaining. After erasing all participants, Facebook redirects you to the team's profile web page.
4. Click the "Leave and Erase this Team" web link.
5. Click "Delete Team."
You should be the group's maker to shut down the team. If the developer left the group, then only a group administrator could remove the team.
