Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for assisting participation in a social network. In one aspect, a method is performed by a system of one or more data processing devices. The method includes receiving, at the system, a historical record of message exchange between an individual and members in a member network, the system determining, for each of the members, whether the individual is likely to want to be related to the respective member, each determination considering the number and transactional characteristics of the message exchange between the individual and the respective member in the historical record, and the system outputting the determinations that the individual is likely to want to be related to at least two of the respective members.

Abstract: A computer-implemented method for handling electronic achievement information involves receiving, from a first user of an achievement aggregation system, a selection of a plurality of achievement tracking services that are operated by organizations that are separate from the operator of the achievement aggregation system; establishing an authenticated electronic communication connection between the achievement aggregator system and each of the one or more achievement tracking services; obtaining from each of the achievement tracking services, information sufficient to characterize one or more achievements obtained by the user; aggregating the information obtained from each of the achievement tracking services into a user achievement profile; and providing the user achievement profile for presentation to one or more users who request profile information about the first user.
