I planned a series of events that required registration. Inevitably, some of them have low or no attendance. I'd like for the ability to indicate that my event has been cancelled, while maintaining the link. For example, I send out an email saying here are the upcoming calls you can register for. Then nobody signs up for the one on Tuesday. On Monday, I'd like to be able to cancel the Tuesday event, but then if someone on Tuesday morning tries to sign up for the Tuesday event because they're reading their email about it, clicking the link should get them to a page that says "this event was cancelled due to lack of interest, please register for a different timeslot" or whatever message I want to deliver. Right now, I believe the only thing I can do is to delete the event, which just results in a broken link if someone clicks it.
