Texting

"Texting" is the practice of sending (short) messages via a cell phone. There are basically three kinds.
 * Standard message sent to another cell phone at a normal number.
 * A message sent to a "shortcode" number, typically 5 or 6 digits. These are sometimes used for television or radio contests.
 * A message sent as e-mail using a typical name@example.com address.

Relevant is the issue of "sexting" where teenagers participate in cybersex over text messages, as well as texting while driving.
