Option to RENEW the event

When the event ends, people who subscribed to the event lose the track of it as the link becomes inaccessible and useless. I would like an option to renew the event and set the new date for it, so that the link doesn't expire. This isn't as good as recurring events, but it allows continuity and persistence between sessions. Also an option to edit and update the session description after it was posted would be good.
