How to make social groups invite only in Odoo 8

Question

I'm trying to make the groups in the "Social Network" module in Odoo 8 invite-only. The issue is when I set a group to private, any user can still follow it. Is it possible to make these groups private, or am I misunderstanding how these groups are supposed to work?

edit- I have tried making the group "invisible" by setting the privacy to "selected group only," but users not in the selected group can still join.

edit- I ended up doing a complete reinstall and could not reproduce my issue. I believe I may have had accidentally changed something in technical features. I accepted the answer below because that is in fact the correct way to do this.

Answer 1

There is no concept as "Invite Only" in Odoo. If you have to hide one group from some specific group of people then you will need to

• set Privacy as " Selected Group Only "

• Then select the group which group can see this group.

• For example,
  Human Resources/Employee

So only those who are assigned the "Employee Rights" of "Human Resources" will be able to see this group and can subscribe to it.
