In Blackboard, if you turn on the setting to allow subscription to discussion forums, students and staff will have the option of receiving emails when new posts are made. In the forum options, select “Allow members to subscribe to forum” and “Include body of post in the email” (see screenshot below). Once this is enabled students and tutors have the ability to opt in or out of the email subscription service.

This video shows how easy it is for students and staff to subscribe to a discussion forum.
