Yes. We provide Announcement boards (platform-wide) as well as Bulletin boards (course-specific).
To access the Announcement Board, click on your name at the top right of the screen and click Announcement Board.
The Announcement Board will look like this.
To add Bulletin Boards to courses, click on Teaching, then Courses. From there, click on the course that you want to add a bulletin board to, then navigate to the General Settings tab.
Scroll down and enable Course Bulletin Board and Learners Can Contribute to Bulletin Board, if you want your learners to be able to post as well.
The Bulletin Board will show up in the course hub.
