In Course Navigation, click the People link.
The People page defaults to the Everyone tab [1], which displays all users in your course.
Once you create a group set in the course, the group set displays as a linked tab for easy access to the group set information [2]. You can click any tab to view a group set for a user group.
You can also click the Options menu [3] and select the View User Groups link [4]. The page will open the first group set in the course.
