Abstract: A system and method for sending custom encoded messages amongst a customized social group. A selection of intended recipients within a subgroup from a list of contacts is received on a client device. It is determined whether all of the selected recipients are capable of receiving a custom encoded message. If it is negative, the method includes sending an invitation email to one or more of the selected recipients. If it is affirmative: the method includes receiving a message from the user intended for the selected recipient. An assignment of a graphical symbol to an alphabet is received from the user. The assignment associating with all of the intended recipients is stored in a memory of the client device. The assignment and the message are transmitted to a remote processor for converting the message to the custom encoded message based on the assignment and transmitting them to the device.
