I understand that thru the "people" tab students can send messages to each other even when taking an exam.....And if you make the people tab unavailable they are cut off from messaging the Instructor. Can you modify this so that we can block student to student messaging during an exam without having to turn it off manually during an exam, then turning it back on after the exam.

So I saw Dave Free's response, but it still involves a manual intervention. So I am posting this again.

My students haven't figured this out yet but it is just a matter of time.
