title: How do I limit one pop up per user, using JavaScript
body: <p>Well I found this code for my blog:</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
  document.body.onclick= function(){ window.open('My site', 'poppage', 'toolbars=0, scrollbars=1, location=0, statusbars=0, menubars=0, resizable=1, width=950, height=650, left = 300, top = 50'); }
  &lt;/script&gt;
  </code></pre>
  
  <p>But since I know nothing about JS, I can't really edit it much.</p>
