    Add settings to messaging feature so instructors can choose settings that best fit the course:

    1. Remove the ability for students to email all other students in a course via course messages. The preferred method would be for the student to only be able to send a message to the instructor.

    2. Give instructors the ability to disable messaging for a course.
