Hello,
Down in the dark depths of Moodle at some stage over the last 2 days I have either checked or unchecked an option that is sending a quiz result by a student (demo site only at the moment) to all other students in that group. I was hoping that someone could shed some light on what settings allow students in a group to receive only their result (and in turn stop all other group members or users from receiving other peoples quiz result). I have read the quiz notification documentation as well as checked messaging setting a few times.
