/* Demo.php V1.03

This script enables users to start a 3jam with up to 5 recipients by specifying names
and mobile numbers of friends. User is presented with a captcha image to verify that
it is not an automated script starting the 3jam.  A verification code will be sent
to the user's phone, which the user is asked to enter on the demo form before the
3jam is started.

To get this script working, fill in your API key below. You can obtain a key at
http://api.3jam.com

For support, contact api@3jam.com.
