title: ajax/JS timed countdown?
body: <p>Let me explain what I'm trying to do.</p>
  
  <p>I want to make a simple box which counts down numbers at intervals I specify.</p>
  
  <p>For example, I'd like to set it to start at 150, and then I want to set it to drop by 15 every 30 seconds.</p>
  
  <p>Is this possible with AJAX/Javascript? If so, could someone point me in the right direction?</p>
  
  <p>Would really appreciate any help on this script, been Googling for hours now! :(</p>
  
  <p>Cheers</p>
