How do I pin a discussion in a course?
You can pin discussions so students will see them at the top of the Discussions index page. Such discussions could include short-run discussions, discussions that only run for a single week, and any other discussions that students should specifically pay attention to. You can also pin discussions within Student Groups.
There are two ways to pin a discussion.
Note: Students do not see the Pinned Discussion heading when there are no pinned discussions.
