How do I lock a Discussion Thread, yet Allow Students to Read Posts?

You can "lock" discussion threads in Blackboard so that new posts are disabled, yet students can read all existing posts. Follow these steps to lock a thread:

1. Open a Forum in the Discussion Board.
2. Verify you are in List View.
3. Select threads to lock (you can select all threads by checking the box to the left of "Date" in the header).
4. Click the "Thread Actions" drop-down list and choose "Lock" for the selected threads. You can unlock the threads in the same way.
