I have a challenge with BC Facebook login on a site am working on. Users are turning off sharing their user profile for the online competition. When a user does this, BC only collects the users name, leaving the email address field blank. I have decided to redirect users to a page with a form to collect additional information for every user using facebook login. However, I want the user to be redirected to the page containing the form only once. Subsequent visit should just redirect the user to the page in the secure zone they desire to vote.
Can Liquid+Cookie help? Or JS. Please how can this be achieved. Not a good js coder. But understands liquid very well.
