title: Alert a message and redirect (or not)
body: <p>lets say i'm making a festival website, and if you enter today you will se the 2010 edition because the 2011 edition it's not finished,</p>
  
  <p>And i want to let to my users know that they are seing the old website and that they will be redirected to the facebook page (untill the new website its finished),</p>
  
  <p>with this code i would be redirecting to our facebook page</p>
  
  <pre><code>&lt;SCRIPT LANGUAGE='JavaScript'&gt;
      window.alert('This is the old edition of our webiste. The new one will be avaliable soon. You would be redirected')
      window.location.href='http://facebook.com/ourfacebookpage';
      &lt;/SCRIPT&gt;
  </code></pre>
  
  <p>But how could i do to allow user staying? (example, cancel / stay here button) so user can see the old website (but he knows it's the old website)</p>
  
  <p>thanks a lot for any idea!</p>
