Abstract: In some examples, a method includes maintaining first electronic contact data for a plurality of users of an interaction system, and relationship data relating to relationships between the plurality of users. The method also includes, using the first electronic contact data and the relationship data, automatically generating composite electronic contact data. The composite electronic contact data includes a first electronic contact record for a first user with which a specific user has a relationship as reflected in the relationship data, and a second electronic contact record for a second user with which the specific user has no relationship as reflected in the relationship data. The composite electronic contact data is presented within the interaction system in a manner that visually distinguishes between the first electronic contact record and the second electronic contact record. The specific user is enabled to initiate an electronic interaction with the second user.
