My request is to NOT send notifications to students until the class has actually started. Currently, if a course is published, and the teacher makes a change (change due dates, etc.), the student is notified.....even if the course hasn't actually started.
At our school, we auto-publish our courses. If teachers make changes to the published class, students are notified. This often happens before the class starts, which causes confusion. Students shouldn't get any notifications about their course (other an the Inbox Messages) until their class actually starts.
