If you need general information on all attendees to an event, not just the ticket buyers, this is the tool for you!
Set-Up
When creating an event, scroll to Order Form & Messaging and click on the tick box next to Require guest information for each ticket. Doing this will allow you to collect information for each attendee.

You have the option to toggle the Collection Method between Standard Info and Enhanced Info.
Standard Info asks for your customer's full name, email address, and phone number.
Enhanced Info lets you choose between all the options below.
You can toggle each one off and on by using the bar on the right-hand side.
