ABSTRACT:
A system for administrating over changes to a record shared by a plurality of users authorized to do so is provided with a resource to officiate over an official version of the record and to communicate with the plurality of users over a medium for non-persistent communications. Typically, this medium is the Internet. In response to a request of a given user, the resource replies with a communication sending a copy of the official version. In consequence of a return by the given user of a request to effect given changes, the resource compares a saved original edition of the sent copy to the official version so if in case of a match the resource effects the given changes to the official version, or else not.
