Lock a discussion forum or topic

Important: For the August 2021/20.21.8 release, your administrator can choose to opt-in to a new workflow that makes it easier for you to set visibility and posting restrictions for discussion forums and topics. If your administrator turns on the new workflow, Locking Options are consolidated with the Availability Start Date and End Date options. For more information on these changes, see the Changes To Availability And Locking Dates For A Consolidated Dates Workflow blog post.
