How to Lock Discussions (prevent posts)
This is useful if you don't want students to be able to continue adding messages to a discussion forum. You must to both steps below to fully lock a forum.
Disallow "New Threads"
This step prevents students from adding new threads to the discussion.
- Go to the Discussion Board in your course.
- Click the "Modify" button for the discussion you wish to lock.
- Under Forum Settings, about half-way down the page, deselect (remove the check marks from) ALL of the options. (To unlock a forum, click on Allow New Threads, and only those other options which you want to use).
- Click Submit.
Disallow additions to existing threads
This step prevents students from adding to existing threads.
- Go to the Discussion Board in your course.
- Go into the forum you wish to lock.
- If you don't see a row of buttons across the top (Select All, Unselect, Invert, etc), click on "Show Options" on the right side of the screen.
- Click "Select All"
- Click "Lock" (To unlock, click Select All, then Unlock).
- Click "OK".
You can confirm that the board is locked by logging into Blackboard with your student account. Try and create a new thread, then try and reply to an existing message in that thread.
