Single-Use Web Form
Maybe I'm missing something here that already exists, but we want the ability for single-use web forms.
For example: I want to conduct a 360-Feedback survey with some of my team members. I send the web form to 30 employees. A week later, I ask around to see who has completed the survey and only 20 people say they've responded, but yet, I have 22 entries on my sheet. (Because the survey / feedback was Anonymous, I am unsure who filled out the form more than once.)
Is there a way to make it so that, once a person fills out a web form, they are unable to fill it out again? (Without having to 'deactivate' the form because I still want it open for others to respond.)
