Instructors can use the People tool in Canvas to view and edit all registered users in the course. To get to the People view, click its tab on the Canvas course menu.
You will then be redirected to the main People page, where you can see a list of everyone who is enrolled in the course as students, teachers and TAs.
To view a user's profile, click their name from the list. In the new page, you will see the users' details. This includes their avatar, recent messages, and services (i.e. Google Docs) they have linked to their Canvas account.
You may also notice that you can do several things from the menu on the right side of the page: send the user a message, see interactions between the user and other students, view the user's Access Report, and see which registered web services the user has.
Back on the main People page, you can see there is a menu on the right side that gives you the option to View User Groups, View Prior Enrollments, View Registered Services, and Manage Users.
Upon clicking View Registered Services, you will see a list of services that users have registered for use within the Canvas course. Users may only see others' registered services if the registered user allows it.
