I want to know that if their are total 3 instructors are enrolled in a course i.e. A, B and C.
Instructor A created the discussion under the course for ex:-"DUMMY" , now 'Instructor B' have gone through the all threads created by students by reading them all, but still when the other 'Instructor A and C' is seeing its displaying all the threads as unread and they are checking from that particular instructor login i.e. 'Instructor B' its showing all as unread.
So i want to know is there bug or how it works, how other instructor is able to track that particular instructor has gone through the threads or not.
