When Other Person is selected an email field displays and when other user selected a user field is displayed. Since I am using this site for registering kids under 18 for safety I have added another field for email address of the parent and would like the option to disable the display of these fields. For the email it validates the email. I would like to be able to shut that validation off when I shut off the email field. Or to allow duplicate emails because 2 kids might attend and have the same parent email address.
