title: How do I implement an SMS service?
body: <p>I have a client that wants the application to be able to send SMS text message alerts to people that have subscribed to the service.  I have seen this done on a lot of sites but I am not aware of what is involved in setting this up.  Does anybody have any experience doing this?  What is involved?</p>
  
  <p>Thanks,
