As the admin, it appears that I have to set teacher permissions to allow them to receive (or not receive) an email when a student submits a quiz. Does "allowing" a teacher to receive e-mails actually mean "forcing" a teacher to receive them?
I don't want to have to turn notifications on or off at the quiz level for each of my teachers. I'd like them to decide which quizzes they want e-mail for, which ones they don't, and then set the setting themselves. What do I need to do to accomplish this?
