This will need some special handling:

CREATE TABLE IF NOT EXISTS /*_*/ep_courses (
<snip>

course_students            BLOB                NOT NULL, --  List of associated students (linking user.user_id)
course_online_ambs         BLOB                NOT NULL, -- List of associated online ambassadors (linking user.user_id)
course_campus_ambs         BLOB                NOT NULL, -- List of associated campus ambassadors (linking user.user_id)
course_instructors         BLOB                NOT NULL, -- List of associated instructors (linking user.user_id)

</snip>

Andrew, are you still planning to work on this?
