Comment 8 for bug 610690

Sounds good to me. Just a few more specifics:

1. Group type open: Any admin can invite users to join - either via their profile page or in bulk.

2. Any group member should be able to send an invite to others he knows to suggest joining a group. Great would be if they don't have to go to the profile page if they want to invite a number of people, but could select from their list of friends as well (similar to what Facebook does) and thus send multiple invites.

3. Group type invite: Again, any admin can invite people individually or in bulk.

4. Turning off the invite: That would be going into the direction of private groups, right?

5. We still keep the controlled membership groups.
