I want to invite a group of people to answer a Google Form, but when they enter their answers I want the answers to be anonymous, not tied to their account or name. Still, I want to be able to see who has answered or not, so I can remind the ones that has not answered.
Basically I want a form with invitation, but I want to store the results anonymously and separate from the list of who's answered and not.
This question is related but not identical to: Anonymous voting on google forms
