We are on Jive SBS 18.104.22.168 8c1 . I am a member in a Private Group with only two members, myself and Sue. I believe our manager, Mary, who retired more than a year ago, was the one who originally created the Private Group. I cannot see any Owner listed anywhere in the group. I have tried to invite our new manager to join the group, but when she responds to the invitation nothing happens.
How can we make a new owner of the Private Group in which I am a member? I have access to the Administrator panel, but am only backup and rarely do anything in that area, so I am a newbie for how to do things.
