Thats great! I tried filling in the quiz and submitting and encountered a Captcha that was partially formatted on screen so I couldn't see all the images, nor the submit button. No way to move forward at all.

I hope you get your site in order, it sounds like a promising market.

You removed the requirement but the field is still there and nothing says the field is optional. I read your reply as "we removed the field".

FWIW I think it's reasonable to collect emails. But at least be honest as to whether the email field required (or not) on the form.

It has been updated to make it clear the field is optional.
