Abstract: One or more aspects of managing information that were previously performed within a private electronic environment are now performed within a public electronic environment off-line from the private environment. This allows the information to be managed at a location that is user-friendly, and relaxes the requirement for a synchronous connection to the private environment. One example of information managed in this manner is a proposal for a contract, such as sales contract.

The two drives (12, 20) are synchronized with one another.
