title: Eventbrite - Pre-populate invited delegate properties
body: <p>I am proposing a solution for a charity and they want to be able to manage conference attendees. I would like to recommend they use Eventbrite for this, but one of their requirements is to store other pieces of attendee information in the form.  I know I can upload a list of delegates for them to invite (it will be a privite, invite only event) but can I also pass more information such as their contact details, a club they are a member of, etc so that it is visible in Eventbrite for the conference organisers?</p>
  
  <p>If so, could you point me to some documentation that details how this is done?</p>
  
  <p>Many thanks</p>
