1. A method for managing a message communication system comprising: providing a token log comprising a data structure that contains a user-extensible set of tokens and implied conditions under which specific tokens are considered valid; creating a new token comprising a set of symbols provided by a system operator that together have no prior functional meaning within the message communication system outside of the token log; storing the new token in the token log together with information that implies one or more conditions under which the token is considered valid, which validity information implies one or more specific actions to be performed when a message accompanied by the new token experiences an event; providing for distributing the new token to one or more external entities; and providing a system operator with the ability to change a validity status of the token; receiving an incoming message with the new token attached; determining the validity status of the new token by attempting to locate the token in the token log and checking the one or more conditions for use; and rejecting the message if the new token was determined to no longer be valid.
