I want to show my survey onto a special (Facebook) group to test my survey if the questions are right, if there are not unneeded questions, and so on.
The answers given by the test respondents are not important, also I don't want to know their email address. I want to give a URL of my survey, where people can fill it.
At this moment, I thought I had set it right, but the preview asks first name, last name and email address.
What did I set wrong?
