Liaison EMP

Would greatly, greatly appreciate a way to have students be able to RSVP "no" to our event invitations. Currently, students will reply to our event invites when they cannot attend, and they keep receiving email reminders from the invite track even though they've already told us they can't come. Would also help us plan for our events with more accuracy when we know how many people have said no versus people who are just ignoring our emails and may become late registrants, etc.
