When a group is marked as private the content within it becomes inaccessible to non-members.

The diagram below illustrates the same groups and content that were described in the group content discussion. However, Group 1 has now been marked as private.

Since Page 1 is associated with a private group it is implicitly hidden from non-members.

The visibility of Page 2 is a little more complex. It is associated with both a private group and a public group. In this case the access control imposed by the private group takes precedence and so Page 2 is hidden from the public and any site users who are not members of Group 1 or Group 2.

Page 3 is only associated with Group 2 and so it is publicly visible.
