CiviCRM Community Forums (archive)

I have built a form for individuals to register for events and some of the people that will be registering will already be in our contact list. If the email that they use for the registration matches an email address in our contact database is there any way to have the registration form prepopulate with that information? Is there anyway of having the Employer box autofill with suggestions as it does when one is doing a search in CiviCRM?
