I'm trying to register my office hours as a repeating event on the course calendar, and I created 3 sets of repeating events. Unfortunately, two of my sets have incorrect info--one has no meeting time, the other has no title (oops!). So my question is---is there a way to edit all of a set of repeating events at once? When I tried, it only acted on the single instance (this week's) instead of all of the events at once. Failing that... is there any easy way to go about deleting 50+50 events so that I can recreate them?
