A computer-implemented method of introducing users of a service includes sending a suggestion to a first user of a service and suggesting an introduction of a second user to a third user of the service. The second and third users are both identified as contacts of the first user in a contact list of the first user and the second and third users satisfy predefined selection criteria with respect to shared contacts, comprising users identified in contact lists of both the second and third users. The method also includes receiving, from the first user, a response to the suggestion; and upon receiving a positive response to the suggestion from the first user, sending the introduction to at least one of the second and third users.

System and method for creating relationships among users of an instant messaging service

Implementations of the present disclosure include obtaining one or more queries, processing data stored in a data store based on at least one query of the one or more queries to identify a plurality of users, the plurality of users sharing a commonality that is a subject of the at least one query, generating one or more query-based social circles, the plurality of users populating a query-based social circle of the one or more query-based social circles, the query-based social circle being directed to the commonality and defining a distribution list for distributing digital content provided by one or more users of the plurality of users, and transmitting social circle data corresponding to the query-based social circle to display a representation of the query-based social circle to at least one user of the plurality of users.

Presence subscriptions for messaging services are managed by automatically subscribing contacts to a user's contact lists based one or more rules, subscription states and contact types. In some embodiments, presence subscriptions are managed by: identifying a set of contacts with respect to an identified user; applying subscription rules to the contacts; selecting a subset of contacts based on one or more subscription rules; and automatically establishing presence subscriptions for the subset of contacts.

Managing presence subscriptions for messaging services

In one embodiment, a computer network-based live chat having three or more participants is hosted. A record of the live chat is archived in a central location accessible by each participant. The archived record is provided to a requesting participant after completion of and/or during the live chat. The requesting participant may be, for example, any one of the three or more participants. The requesting participant may make the request from any remote location in communication with the central location. In another embodiment, a system for enabling access to a multi-user chat archive includes a multi-user instant messaging (IM) server, a state manager, an archive database, and an archive manager. The archive database is configured to store an archived record of the live chat in a central location. In this embodiment, the central location is accessible by each of the chat participants from any remote location in communication with the central location.

Multi-user chat search and access to chat archive

Methods and apparatuses to tell humans and machines apart. In one embodiment, automated determination of whether a human or machine is at the other end of a communication channel is based on whether the correct response to a challenge/question is received from the other end of the communication channel. The challenge is provided in a non-image format, such as a text based questions or a sound clip, to prevent abuses of the communication system by computer software robots. The communication system may be primarily for text and/or voice communications, or be such that the rendering image-based challenges can cause significant disruption in normal flow of usage. In one example, the challenge includes deliberately generated random misspelling. In one example, the challenge is context sensitive, factual based, and/or instructive of an operation in a natural language to obtain a result.
