i plan to integrate a questionnaire or feedback form in my Worpress site. The form is not the problem, then this is very easy with the plugin. My problem is, the user can fill out again the form, when he is going back to to the questionnaire site. I could not found a option to block to fill out again the form for the next hours, days, months, .....
Is there a way, so a user can only fill out the form once time?
Thanks for informations!
