When you create a group, you can completely control its privacy. There are three different access levels:

• Open: For Open groups, everyone on Facebook can view the group and join. The group will appear in search results and all content (e.g., photos, videos and discussions) is visible to anyone viewing the group.
  
  
• Closed: For Closed groups, everyone on Facebook can see the name and members of the group, but only group members can view content in the group. Unless you're added to the group by another member, you'll need to ask to join when viewing the group. You'll become a member when your request is approved.
  
  
• Secret: These groups cannot be found in searches, and non-members can’t see anything about the group, including its name and membership list. The name of the group will not display on the profiles (timelines) of members. To join a secret group, you need to be added by a member of the group.

If you're an admin of a group with fewer than 250 people, learn how to change your group's privacy setting.

If you're an admin of a group with fewer than 250 people, you can change your group's privacy setting:

1. Click at the top right corner of the group.
2. Select Edit Group from the dropdown menu.
3. Pick a new group privacy option from the Privacy dropdown menu and click Save. All members of the group will receive a notification that the settings have changed.

When non-friends are in the same group as you, this does not allow them to see any more of your profile (timeline) information than your privacy settings allow.

The functionality of approving a group membership is not available. Similar to being tagged in a photo, you can only be added to a group by one of your friends. When a friend adds you to a group, a story in the group (and in News Feed for Open or Closed groups) will indicate that your friend has added you to a group.

Please keep in mind:

• Only your friends can add you to groups.
• When a friend adds you to a group, you'll get a notification right away.
• You can leave a group anytime. To do so, just go to the group page and click "Leave Group" in the right-hand column. Once you leave a group, you can't be added by anyone else unless you explicitly request to be re-added.

1. Go to the group you want to report
   
2. Click at the top right corner
   
   
3. Pick Report Group from the dropdown menu

Groups containing drug-related, nudity, or other graphic or sexually suggestive content are not allowed, nor are groups that promote violence or that attack an individual or group. For information about what we allow and don’t allow on Facebook, please read our Community Standards.

Facebook reviews reports to determine whether or not the content violates our Terms and will take appropriate action. Rest assured that these reports will be kept confidential.

Unfortunately, you will not be able to send a second group invitation to the same friend. The person will have to request to join the group again.

Stories from open groups may appear in your News Feed since open groups are public.
