    You can set up unique submissions for your form. There are three possible choices:

    1. No check - this is the default

    2. Loose check - this uses cookies to tell if a user has already submitted your form. But only lasts until the browser cache is cleared

    3. Strict check - this uses cookies and also checks the users ip address


    Heres a complete guide:
