Google Groups, a tool for a team of users to quickly collaborate with one another either via email, or any of Google's various applications, is available with Google Apps for the University of Minnesota.
Google Groups is all about helping users connect with people, access information, and communicate effectively over email and on the web. With members of your team all in the same group, Google Groups makes it easy for sharing things like Google Calendars and Docs with one another.
Users are assigned roles that determine what he or she can do within a group. Participants subscribe to groups and participate in group discussions, and group managers create new groups and manage group members, discussions, and other settings.
Note, in order to get your group built in to UMD mail routing, you should request a group through the University of Minnesota Web form (and not through the google groups home page) by following this link: Requesting a Group.
