Is it possible for a group to have multiple owners? If so how would one do that?
Sure - just set several members to the role Administrator. Administrator = Owner for a group.
Here are the steps for that:
1. Invite and get the user to join the group
2. Go into the group management section (4.5.x - in the Actions menu; 5.0.x - in the Manage drop down) and choose the option to manage the group members
3. Change the user's role from Member to Administrator
