Unsubscribe List

It would be nice to know all the participants that did unsubscribe for an event. This helps with getting better analytics.

It also give us better info when users, that did unsubscribe, still show up at an event last minute with a PDF ticket.

Also since there is no way to look at who did unsubscribe we can't re-target them or survey them to find out the reason for unsubscribing to the event.

Maybe add a status unsubscribed just like there is one for denied, incomplete, complete etc.

Thanks
