<h4>Simply limit form submissions per user</h4>
<p>You can set a timeout for submissions per user so you can make sure a user doesn\’t submit a form too often. This is especially useful if you use NinjaForms for any kind of votings for example when you create a photo contest with <a href="http://etzelstorfer.com/en/downloads/ninja-forms-multimedia-field/" rel="nofollow ugc">Ninja Forms Multimedia Fields</a>.</p>
<h4>No need to register users</h4>
<p>Of course a cookie is not as save as validating logged in users but it is fast and simple and you don\’t force your visitors to create an account.</p>
<h4>For all kind of votings and polls</h4>
