With User-Managed Groups for Google Apps, you can enhance messaging and collaboration among your school staff, teachers, students and even parents.
With this service, users can create their own groups, so they can further customize their communications -- without the need to contact the domain administrator. You can give this privilege to users and remove it at any time. If you let users create their own groups, they can managed their groups to control who can join, send messages, invite members, view members, and view discussion archives.
Instructors can improve communications among students by creating groups for their classes, subjects, and grade levels. Students can use groups to reach other students in their classes, sports teams, clubs, and extracurricular activities.
You control what users can do
As a Google Apps administrator, you can enable or disable the Google Groups for Business service whenever you want. If the service is enabled, you still retain full control over the groups in your organization. You can also prevent users from adding external members to their groups, edit or delete users' groups, or even stop users from creating their own groups altogether.
Please note: If multiple domains are associated with your organization's Google Apps account, only users in your primary domain can use the user-managed groups service.
