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.
If you pin several discussions to the Pinned Discussion section, you can move or reorder discussions within the section.
Note: Students do not see the Pinned Discussions section when the page does not include pinned discussions.
To unpin a discussion, locate the discussion and click the Options icon , then click the Unpin link .
