Prevent double registrations

Please be aware that Lyyti is developed constantly and your view might not match 100% with the view described in this article. 

Using personal registration links prevents double registrations. However, if you need to use the event's open registration link and you wish to avoid double registrations, you can modify the event's settings so that a given e-mail address can only be used once for registration. 

To enable this setting, go to your event and in the left menu, click Registration page and modify the E-mail question. Click Advanced settings > What can participants do? > Only one registration with the same e-mail address allowed. Save.
