19 . The gateway of claim 11 , wherein the message generated by the client associated with the on-line player is addressed to a character name of the off-line player.

20 . A gateway comprising one or more computing devices, the gateway being configured to:

receive a notification message from a gaming server that implements a virtual world, wherein the notification message characterizes a location in the virtual world and the notification message is sent in response to a loss of communication with a client operated by a given player; and

generate a short message addressed to a mobile device associated with the given player in response to the notification message, wherein the short message include a link accessible by a mobile client stored on the mobile device, wherein the link directs the mobile client to the gaming server.

21 . A method comprising:

receive a notification message from a gaming server that implements a virtual world, wherein the notification message includes content directed to an off-line player of the virtual world;

generate an original short message addressed to a mobile device associated with the off-line player in response to the notification message, wherein a FROM field of the original short message includes a dynamic code that uniquely identifies the original short message; and
