Yammer

Yammer (https://www.yammer.com/) is a private and secure social networking tool designed specifically for businesses and organizations. Users are automatically added to a social network when they enroll using their organization’s email address (e.g. @uwm.edu). Instructors could use Yammer to cultivate a social learning environment that lives apart from public sites like Facebook, and students could join Yammer to share class- and campus-wide information and to collaborate in an online environment. Free apps for the iPhone and other mobile devices are available.
