Abstract: A user may receive one or more text messages after the user is authorized. The potential user can opt in through a web page in one embodiment. Once the potential user sends an initial request, the user may receive a first text message containing an authorization code on their mobile phone. The user may enter the authorization code back to a web page. Receipt of the authorization code may trigger the phone number of the potential user to be added to a list of authorized text message receivers. One or more text messages may then be sent to authorized phone numbers on the list.
