CiviCRM Community Forums (archive)

Hello,
I use CIVIEVENT / JOOMLA to allow registrations with 2 profiles. During the registration process, the participants have to fill in 15 fields (normal and custom fields). My participants are fed up with filling in all these fields each time they apply for an event. Most of them need to register to events several times. So, is there a way to set up events with a registration form of an unique email field. If the email field is not known, the participant is redirected to create the whole civicrm account. I don't want to create a Joomla account, but I want to create a CIVICRM profile only if the email address is not known. Is this possible ? Thanks...
