When a person selects more than 1 person for the event, how can I require the email (and ideally the first name and last name) to be different? Currently a person can use the same email address and same name for each person (example – if they select a QTY of 3 people).
The questions system allows you to configure the questions for Additional Registrants. You can set the forms system to ask for the contact information or any custom questions. See here: https://eventespresso.com/wiki/questions/#40_
