New Feature: Closed Groups
The current groups system is public, meaning that anyone can see and subscribe to any group on the system.
We need to add a feature that groups should be public, closed, and secret.
Public: is the current default and the group and posts are open ,viewable and searchable. Any user can access, join. Closed: Group and its description is viewable but posts are not. Users must be approved for access. Private: Like Closed groups but the group, and it's description are not viewable to anyone not an admin/moderator/group-owner/member.
