Access codes and instructor self-signup permissions now apply to Learning Management System (Blackboard, Canvas, etc.) integrations. 

If an access code is enabled, users will be prompted to enter the access code in order to join a class on piazza.com or through their Learning Management System. 

If instructor self-signup is disabled, an instructor that is already enrolled in the class can re-enable instructor self-signup, approve the enrollment requests of another instructor, or manually enroll the instructor(s) via the Manage Class tab. 

Contact us at help@piazza.com if you have any other questions!
