Abstract: A method for generating a page for charitable fund raising over a network. A user creates a definition for a fund raising event and transfers the definition to a fund raising server, which generates event information (e.g., an event record). The user selects a non-profit organization and transfers the selection to the fund raising server, which generates organization information (e.g., organization record). The fund raising server generates a mapping (e.g., mapping record) of the event information to the organization information. The fund raising server creates a fund raising page accessible over the network based on input from the user and providing a link from the fund raising page to the mapping. The user is also able to nominate a non-profit organization which is not yet available for selection, which is then vetted by the fund raising server.
