TOPIC: Multiple registrations/events issues

I submitted a ticket regarding this issue, and here was my answer - hope this helps

Hello. If you are using the cart for multiple event registration, each registration will use a fresh form. It will NOT use any data from the previous registration. To help this, you should use Community Builder or JomSocial integration. Then you can have users login and then have data auto-populate FROM the user profile into the registration forms. That gives a more user-friendly experience.
