Learn@UW/D2L - Restoring Deleted Discussion Forums and Topics
An instructor of a course can restore discussion forums and topics along with any posts that had been contributed to the deleted topics.
To restore a discussion forum or topic to your course that has been deleted, proceed as follows:
Select the Discussion tool in your course.
Use the drop-down by "More Actions" near the upper left corner to select Restore.
Click on the Restore button by the forum or topic that has been deleted in the table.
If you restore a forum, you will be able to selectively restore any or all of the topics in contained when the forum was deleted. For example:
Any restored topics will contain the posts and threads that were present at the time the topics were deleted.
If more than one forum or topic in your course have been deleted, you can click on additional Restore buttons in the "Restore Forums and Topics" table to restore other forums and topics.
