How do I create a private group?
Private groups are great if you have a small group of friends or users that can be included by invite only. When creating a new group, toggle the privacy switch on the Post page (NOTE: groups CANNOT be made public after they’ve been made private by the owner or an app moderator). To invite someone to an existing groups, click the "Add/+” button under Add Friends on the bottom of the Post page. Any active member of a private room can add new friends to the private group.
