I would love to see a feature that checks the users input into an event registration form against the existing registrants, and based on, let’s say candidate first name, last name and email address, if they are already registered the user is directed to a message that says so. As of now I end up with people registering multiple times, and when I run a report to get a count of how many people are attending I have to sift through and take out duplicates to get an accurate number, or else delete them from the event registries which is time consuming.
