Demand unique email addresses in the registration

To avoid double bookings, you can set it so that it is not possible to book and enter the same email address more than once. It can be set for all categories with confirmed bookings or per category.

This is how you set that it is not possible to register several people with the same email address for the entire event

This setting then validates unique email addresses between all categories that have confirmed bookings (ie not for import, no thanks or unregistered categories.

1. Log on to the admin for your event 
2. Go to Settings in the left menu 
3. Under General settings - check the box for Demand unique email addresses across all registration forms 
4. Scroll down and click on Save
5. Now there will be a message appearing in the registration if a person tries to book with an email address that is already used for another booking for the event.
