Product Request: We run a monthly series of webinars; each month about 40% of registrants are first timers. I need to capture their details (including some custom questions I've added), but I want to avoid asking the 60% of previous attendees to resubmit all their details everytime. My ideal scenario is to have a first question "Have you registered before" if the answer is yes the questionnaire proceeds to a later-numbered question (eg the last).
