Abstract: In some examples, an instant message addressed to an intended instant messaging recipient may be forwarded to the recipient's mobile telephone when the recipient's mobile telephone number is known to the instant message sender. In one example, an instant message is forwarded to the intended recipient's mobile telephone number when the instant message sender's contact information for the intended recipient includes an instant message address (e.g., a screen name or other type of instant message identifier) and a mobile telephone number, without dependence upon the intended recipient's presence on the instant message (IM) system or through actual login or registration with an IM forwarding service. In another example, an instant message addressed to an intended instant messaging recipient is forwarded to the recipient's mobile telephone when the recipient is known to the instant message sender.

Abstract: Enabling a recipient to control presentation of an audio identifier informing the recipient of an arrival of a digital communication from a sender in a communication session includes receiving a digital communication from a sender directed to a recipient. A sender-designated first audio identifier or sender-related information that identifies the sender to the recipient is accessed upon arrival of the digital communication. The first audio identifier or sender-related information is presented to the recipient contemporaneous with receipt of the digital communication. The recipient is able to specify, upon presentation of the first audio identifier or sender-related information, whether to enable subsequent presentation of the first audio identifier prior to or concurrent with receipt of a future digital communication from the sender.

Abstract: Audibly informing a recipient of an arrival of a digital communication from a sender includes receiving a digital communication from a sender directed to a recipient and determining whether the digital communication is associated with an audio identifier that identifies the sender of the digital communication and that is designated by the sender of the digital communication. Perception by the recipient of the audio identifier is conditioned on whether the digital communication is determined to be associated with the audio identifier. The audio identifier is perceived prior to or concurrent with perception of the digital communication by the recipient.

Abstract: Providing supplemental contact information for an individual referenced in an electronic message typically includes receiving an electronic message, examining the electronic message, detecting an identifier for a referenced individual contained in the electronic message, and making supplemental contact information for the referenced individual available to a recipient of the electronic message. The supplemental contact information may include information that is in addition to information contained in the electronic message. The supplemental contact information may include at least one of an e-mail address, a screen name, a telephone number, a facsimile number, and a mailing address each of which is associated with the referenced individual.

Abstract: A sender's degrees of separation from a recipient may be used to aid in spam filtering or to otherwise handle a communication. The “degrees of separation” represent a metric used to quantify whether/how the recipient is linked to the sender through intermediary people or other entities. For example, a recipient may know a first user (first degree of separation) and the first user may know a second user (second degree of separation) who knows the sender of an e-mail. In this case, the sender is separated from the recipient by two degrees of separation (by two other contact). A level of “trust” or “legitimacy” about a sender's communication can be inferred by looking at whether the sender is linked to an intended recipient. Typically, user contact lists are evaluated to determine the number of degrees (or hops) are required to link or relate two users.

Abstract: Controlling the volume of an audible alert associated with an instant messaging communications session includes rendering, on a first instant messaging user system, an instant messaging application user interface for an instant messaging communications session involving at least a first instant messaging user and a second instant messaging user, receiving notification of an event related to the instant messaging communications session, determining a characteristic of the event, accessing an audible alert to be rendered to signal existence of the event, adjusting based upon the determined characteristic of the event a volume of the audible alert corresponding to the event, and rendering the audible alert to signal existence of the event.

Abstract: Social network information may be shared across online service providers. Thus, one online service provider M that maintains a membership separate from a second online service provider N may nevertheless use the social network maintained by the second online service provider N to tailor content and/or services based on such social network information.

Abstract: A client system is configured to submit a request to a first instant messaging system for access to the first instant messaging service The request includes an online identity that is currently being used to access a second instant messaging service associated with the second instant messaging system. The second instant messaging system is configured to send a message to the first instant messaging system that indicates the online identity is currently being used to access a second instant messaging service associated with the second instant messaging system. The first instant messaging system maintains a profile that is updated to indicate that the online identity is currently being used to access the first instant messaging service and, in response to the message, the profile is also updated to indicate that the online identity is currently begin used to access the second instant messaging service.

Abstract: Communicating between electronic devices involves sending messages between the electronic devices. An original message having an original source indicator and an intended destination indicator identified is sent. A reply to that original message is sent by the recipient of the original message. The reply message has a reply source indicator and a reply destination indicator. A communication based on the reply message is sent. The communication based on the reply message has a reply source indicator that is the same as the intended destination indicator identified by the sender of the original message. In one example, a message is sent from computer operating an instant messaging program and forwarded to a mobile telephone. The reply sent from the mobile telephone is provided to the sender of the original message without revealing the telephone number of the mobile telephone to which the original instant message was forwarded.

Abstract: A graphical user interface on a display device of a computer enables communications using a computer service. The graphical user interface includes a list of potential message recipients selected by a user as significant to the user. The graphical user interface also includes a mobile device identifier associated with one or more of the listed potential message recipients and a user account identifier associated with one or more of the listed potential message recipients. At least one of the listed potential recipients includes a mobile device identifier as the only available conduit for data delivery to the potential message recipient using the computer service.

Abstract: Electronic messages may be processed using a stamp authority by receiving an electronic message, identifying a stamp associated the message, determining if the stamp is valid, and, if the stamp is determined to be valid, distinguishing the message from messages with which a valid stamp is not identified.

Abstract: Systems and techniques for transferring electronic data between users of a communications system include a host system structured and arranged to receive and deliver messages of various types between users of the communications system. The host system includes an instant messaging network; a mail gateway; and a configuring network in communication with both the instant messaging network and the mail gateway. The instant messaging network enables instant messaging communication between users of the communications system and has the capability to monitor whether a certain user is capable of receiving an instant message at a particular moment. The mail gateway receives and delivers e-mail messages to users of the communications system. The configuring network is dedicated to automatically configuring instant messaging communication between an intended recipient of an e-mail message and the sender of the e-mail message.

Abstract: Informing a user of a large scale network dynamically of other network users includes determining dynamically an online context of the user. Other users presently within the online context of the user are identified and trait information is stored that is related essentially only to the user or to the other users in a users store associated with the online context. The user is informed dynamically of the other users based on the stored trait information, such as, for example, an age or other demographic identifier, or information indicative of an expertise, interest, preference, user type and/or other quality of the user or of the other individual.

Abstract: An electronic message may be reconfigured to effect an enhanced notification using an input interface to receive at least one electronic message created by or on behalf of a message source for delivery to an intended recipient. A matching engine determines whether the electronic message corresponds to a predetermined definition of an enhanced notification. An enhancement engine reconfigures the electronic message to the enhanced notification if stored information related to the intended recipient indicates that the intended recipient is subscribed to receive the enhanced notification. Reconfiguring the electronic message may include reconfiguring the message to provide special handling, routing or presentation.

Abstract: Systems and methods are disclosed for tracking and displaying the logon status of selected co-users of an on-line or network system in real time to a tracking user in a unique graphical interface. The invention provides user definable on-line co-user lists, or “buddy lists,” which track specific co-users in real-time automatically. When a user logs on to a system, one or more of the user's buddy lists are presented to the buddy list system. The buddy list system attempts to match co-users currently logged into the system with the entries on the user's buddy list. Any matches are displayed to the user. As co-users logon and logoff, a user's buddy list is updated to reflect these changes. An indication can also be added to show that a co-user just logged on or just left the system.
