Hello everyone. I'm wondering if it is possible to have a public survey and ask users for their email address. Then once a survey has been sent using that email address, you can't resubmit the survey with the same email address.
What I'm doing is setting up the survey much like a ballet voting system and using email address to deter multiple submissions by the same user as well as collect email address. If this is possible, any direction on how to do this would be great!
