Abstract: A method of registering information for a user in a centralized user database (24) accessible by a plurality of subscribers. The method comprises establishing a first internet site (12) having a first plurality of identity fields (14) for inputting user information into and a second internet site (32) having a second plurality of identity fields (34) and linking both to the centralized user database (24). The method further includes a master list of identity fields (26) for comparing the first plurality of identity fields (14) and the second plurality of identity fields (34). The method is characterized by populating the user information registered in the centralized user database (24) from the first internet site (12) to the second plurality of identity fields (34) on the second internet site (32). The second internet site (32) may have one additional identity field (40) different than the first plurality of identity fields (14) and identity fields which are unique to the second internet site (32).
