Abstract: A method for providing electronic checklists to subscribers including the steps of: maintaining an electronic store of publisher checklists in communication with a first computational device such as a server; operating the first computational device to produce subscriber checklists, derived from the publisher checklists, upon remote subscriber machines across a data network; operating the first computational device to monitor for reception of modifications to the subscriber checklists from the remote subscriber machines across the data network; operating the first computational device to mix said modifications from subscribers with corresponding subscriber checklists of said subscribers; and operating the first computational device to produce the subscriber checklists incorporating the mixed modifications upon the remote machines.
