I'm looking for assistance setting up Social Groups and Group Spaces. I've run into several problems and can't find solutions.

1) Can't figure out how to see a list of members in Group Spaces

2) Can't set up additional features associated with Group Spaces (only the first, Answers, works)

3) Only Admin roles are able to set up a group in Social Groups

4) When I create a private group in Social Groups, all the group activity is posted on the main page for general users to see

5) Is there a way to send an invitation to join a group in Social Groups?

6) There are no notifications sent by email for either of these modules. I would like the group owner to be notified when there is someone new to approve, and for users to be notified by email when they are invited to join a group.

There are probably other things that I just can't remember at the moment.
