You can create a course announcement a few different ways:

• From the Announcements widget, click on the “Create an announcement” link to begin composing a New Announcement.
• From the course Navbar, click on “Course Tools” > “Announcements” and click on the “New Announcement” button.

Please note that each student and instructor can manage their own Brightspace notification settings. To do this, click on your name in the upper right corner and click “Notifications.” By default, you will receive an email notification when a new Announcement is made or updated. Check the appropriate box to receive notifications for those actions. Remember to click on the “Save” button when you’re done. More about Notifications can be found at the “Change personal settings in Brightspace” official Brightspace Community documentation.

More information about how to create a welcome message using the Announcements widget can be found at Brightspace’s official help documentation.
