Because of the current situation, we require pre-registration for most of our events. We do have setup the system to send an email to the person who made the registration, but I was wondering how can I show current registration for a specific person.

 What I need is just to be able to show current registrations. And maybe the possibility of cancelling a pre-registration (if they decide not to come)

Is it possible? Any hint you can give me?

Thank you so much!
