OG Private Content For Other Groups

How many times have you created a private content just to see your group, but would like some other group would be able to view this content without editing it and others can not see private content in your group?

This module provides the ability to give permission to display on a particular node, which was set to private for the group, a group to which the user is not a member. The groups have chosen only the ability to view, without compromising system security.
