From now on, I can upgrade your site so it can be able to send SMS automatically.
Why? People is not always connected to the Internet, but they always carry their cell phones with them. That's why this service is so useful. You can't be sure they'll read an email from you, but most people reads all SMS they receive before deleting them. If you want to be extra-sure they are properly notified, you can send both an e-mail and an SMS, not a problem.
