Is a unique view possible?

Hi, 

I'd like to set my form up so that the user doesn't see it again if they've clicked to close it before. I've changed the submissions already so that the same users cannot submit multiple forms, but as far as I understand it, this will only stop appearing if they've already submitted. 

Please can you advise on this?

Thanks

I don't believe this is possible. The form doesn't record the IP address until it is submitted. 

Best you can do is enable unique submissions or a unique question:

How to set Form Limits Based on a Unique Question  

Or you could create two forms. First one takes the name and email address. If the email address is unique you can have it load the second form. You do this by setting the location of the second form as a thank you page.
