In this session we will explore features, functionality, and user experience of Mattermost, a free chat and collaboration tool hosted at TRU. An increasingly popular application for team-based projects, Mattermost will be valuable for teachers, students, or anyone who is involved in distributed teamwork for projects of any scale. As it is hosted at TRU, it is compliant with privacy legislation (FIPPA). Participants will have the opportunity to initiate an instance of Mattermost; populate this with files and links; create channels; and invite additional users— including colleagues outside of TRU. TRU use cases will explored so participants can see how Mattermost might fit in with their projects or course delivery.
