Members-only worlds are membership-based communities where like-minded people can come together and enjoy a shared experience. In order to join a members-only world, you must be sent an invite by a member of the world, or you must request to join a world and have your request approved by a creator or admin.
To manage an invitation to join a members-only world:
When you accept an invitation to join a members-only world, or your request to join has been accepted by the world creator or admin, you will see a new tab on your Worlds menu called My membership worlds. From this tab, you can view and access all of the worlds where you are a member.
