The Global Activity Stream contains recent notifications from all of your courses, including announcements, discussions, assignments, and conversations. This activity stream helps you see all recent activity in your courses and easily ask questions and post to discussion forums. Unlike course cards, the activity stream does not mimic the visibility of Course Navigation links.
Activities are indicated by activity type and display an icon [1] for the activity. Each activity also includes the name of its associated course [2].
New activity in your account is indicated by an unread icon [3]. Discussions and Announcements indicate new activity items published in a course, and Conversations indicate a new message received from a user in a course. Recent Activity items remain for four weeks.
