I'm looking to be able to have a group with limited membership (a private group) that can have public documents that non-group members can see. When I set a group to be private non-members cannot look at the docs directory for that group (even if documents within are marked as readable by anyone). A public group does not work because there is no limiter on membership, so anyone can join the group and see other documents that are restricted to the group. What I'm looking for is a way to separate group membership and privacy from groups. Does anyone know if there is a plugin/fix available that allows this?
