A server in communication with the data network receives the personal electronic document from a first computer in communication with the data network. The personal electronic document is constructed using the document design application. The personal electronic document is associated with the user. The personal electronic document is stored as data on a storage medium in communication with the data network. Advertisement information provided by the carrier is inserted in the personal electronic document. A second computer in communication with the data network is provided access over the data network to the personal electronic document stored on the storage medium. The second computer is associated with a visitor of the personal electronic document.
