I have found it to be really frustrating in keeping up with things if I can’t get e-mail notification when things happen in courses that I am taking or teaching. I really do need something to call me back into the fray every once in a while when something good just happened.
Here is the Moodle doc that tells you exactly how to get e-mail notifications for teachers and students when things have been done in your courses.
The resuting e-mail is awesome. It not only tells you who took it but also gives you a link to review the attempt and give feedback right away. Good stuff.
