My groups : Lists all the groups you own. You have full power over these groups
Groups I’m member of: Lists all groups of which you are a member for one reason or another.
Groups I administrate: Lists all groups of which you are both member and admin. You can modify the members of these groups.
All groups : Lists all groups available in the application, except those marked as hidden
