You can assign one or more group administrators to any user group. Group administrators can manage the group settings, add or remove members, and start chat conversations for their user groups. You can also assign a whole user group as administrator of another user group. An administrator does not have to be a member of the group in order to be assigned as an administrator. Assign an administrator to ensure your user groups stay up-to-date.
