How do I make an Announcement in my course?
Announcements are simple to make in Canvas.
Note: In your notification preferences, you can choose to receive notifications for announcements created by you as well as replies to announcements you've created.
Type a title for the announcement in the topic title field  and add content in the Rich Content Editor .
Click the Save button to post the announcement.
Note: Unless you are using the delay posting option in Announcements, once you click Save, your announcement will immediately be posted in your course.
Once you save the announcement, it will appear on the Announcements Index Page.
