Hi! We are pleased that registrants for events have the option to unregister, and it seems they use it. However, it has been difficult to automate any sort of notification for when this happens. For example, when a student registers for an event, we get a triggered to-do so that we can enter some essential information back in WebAdmit. A triggered to-do for unregistration would be very helpful. Another way to sum up my request would be that whatever capabilities the system has based on recognizing a registrant - the system also has based on recognizing unregistrants.
