I have an instructor who is using events to let his sections know when to meet and where. However, he didn't make the events different times for each section and now wants to do that. He doesn't want 14 notifications to go out for each student that the time has changed. The problem is that the course has started and there are grades in the grade book already so we cant unpublish the course. Any ideas on how to keep from spamming all 300 students multiple time today?
