The Activity Stream shows new announcements, upcoming due dates, assignments, and exams. It's a good way to get a quick snapshot of what's new and upcoming.
You can filter notifications shown on your Stream:
- Select an option from the Filter drop-down menu on the top right and make a selection.
You can personalize which notifications you receive:
- Click on the settings icon in the top right to change these settings.
- See more on Blackboard's Support page: Edit Notification Settings
You can also Dismiss the Important notifications from the top when they have passed, by clicking the Dismiss button to the right of each item.
For more, see the Blackboard help page: Activity Stream.
