Is this scenario possible with Gravity forms? We give a personal link to the form to a customer. He/She will fill in his address and submit it to us so that we can send a voucher through snail mail. That form (or link to the form) cannot be used again by the said customer to avoid multiple vouchers. How do we make sure that the form is used once per person?<br /> Thanks! </p>
