Discussion Boards: Clearing Threads and Forums After a Course Copy
Discussion Board Forums will copy from one course to another. The Threads from the previous course will also copy over with the username Anonymous.
To prevent the current class from reading these comments, you will need to clear them.
Go to Course Management>Discussion Board.
Open the Forum to view the Threads.
Check the box (underlined in red) in front of the Thread(s) to mark for removal.
Select the Delete option (highlighted in yellow) to complete the action.
If Forums need to be deleted, the process is similar, but use caution and be sure there are no Threads or Replies to threads that need grading or have been graded in a live course section.
