How do I delete my community (group, public page, event)?

1. Remove all of its content: members, photo albums, discussion boards, videos, tracks and other information.
2. If it's a group, make it private. If it's a public page, convert it to a group using the button under the community's main photo and then make the group private.
3. Leave the community by clicking You’re a member → Leave community.

After doing this, you can just forget about the community. However, community mentions and comments made as the community will remain unless you delete them separately.
