    I would like to ensure that people only submit a form one time. Is this possible?

    Yes, this can be made possible by configuring your form's Unique Submissions settings.

    1.  Click Setup & Embed

    2.  Click Preferences button

    3.  Select Advanced Settings in the Preferences window

    4.  Set Unique Submissions to either Loose Check or Strict Check


    Loose Check - uses cookies to identify if a user has submitted form. This can be easily bypassed by the user by deleting his browser cookies.

    IP Address -  uses IP information. The only way to bypass this is to change IP Address.
