Abstract: A communications service provider provides wireless access to a packetized data network, such as the Internet. The service provider includes a server computer. The server computer is connected to the network, which is at least in part a wired network. The wired network is connected to a cellular wireless communications system. The server computer communicates with an e-mail server of the network according to standard network protocols. E-mail messages are served by the e-mail server to the server computer. The e-mail messages are manipulated and maintained at the server computer until requested by an e-mail application of a client device, such as a wireless device. An interface resident at the client device communicates with the e-mail application and the server computer. The interface serves to translate from and into optimized protocols for communications between the interface and the server computer.

Abstract: A system and method that includes the use of a knowledge delivery computer program stored in computer-readable form on a tangible storage medium for delivering concepts from a configuration data base to a user. An author can create the configuration data base using the knowledge delivery computer program so that the configuration includes a plurality of concepts and, optionally, a plurality of problems associated with the concepts. As the author creates the concepts within the configuration, the knowledge delivery software allows the author to create a taxonomy that defines the relationships between the concepts. The knowledge delivery software can then automatically generate a pedagogy for the configuration based on the configuration taxonomy that defines how the concepts will be delivered to the user. The knowledge delivery software can facilitate the delivery of the content within the configuration to a user according to the pedagogy.
