Abstract: Audibly identifying an event includes enabling selection of a first sound based upon an identifier. The identifier enables identification of an entity related to the event. A notification of an occurrence of the event is received. The notification includes the identifier. An intended recipient is alerted of the event by playing, in response to the notification, at least a portion of the first sound and at least a portion of a second sound that is related to the event.

Abstract: Organizing a participant list includes maintaining a participant list of users of an electronic communications system to be used by a first user of the electronic communications system. Communications strengths between the first user and each of the users included in the participant list are determined. The users included in the participant list are organized based on the corresponding communications strengths. Communications strengths may be determined for users included in a group within a participant list, and the users within the group may be organized within the group based on communications strength. An additional group in the participant list in which some or all of the users included in the participant list are organized based on communications strength may be provided.

The embedded multimedia object or the attached multimedia object is separated from the electronic message. The separated multimedia object is automatically saved to a repository for subsequent use by a user and the user is able to select the multimedia object from the repository for subsequent use.

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: 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: An incoming message and an indication of a sender-specified destination for the incoming message are received. In addition, a determination is made as to whether a mobile telephone number is known by the sender to be associated with the sender-specified destination. If a mobile telephone number is known by the sender to be associated with the sender-specified destination, a first message that is based on the incoming message is sent to the mobile telephone number. Furthermore, a second message is sent to the mobile telephone number that indicates that the first message was sent to the mobile telephone number based on a determination that the mobile telephone number is known by the sender to be associated with the sender-specified destination.

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: A method for transmitting data to one or more users of a communications system by establishing a connection with one or more users; designating targeting rules applicable to online users; acquiring context information of online users; applying the targeting rules to the context information to identify targeted online users; and sending data to the targeted online users.

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: The performance of a network system having one or more requestor nodes, one or more provider nodes, and one or more intermediate nodes is improved by determining the digital signature of a received file, looking up the digital signature in an index of signatures, and forwarding a previously compressed version of the requested file when the digital signature is found in the index of signatures.

Abstract: Personalizing communications for a first communication platform includes accessing status information for communication sessions by a communication identity that leverage a first communication platform other than an instant messaging platform. A participant list associated with the communication identity and the first communication platform is passively configured to persistently reflect a list of participant identities from communication sessions in which the communication identity recently participated using the communication platform.

Abstract: Techniques are described for forwarding an instant message addressed to an intended instant messaging recipient 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: 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: Providing location information to a supervisory user includes providing a parental control, using a computer automatically to determine a location of a subordinate user, and storing location information indicative of the location of the subordinate user in a database. A request of the supervisory user to locate the subordinate user is received and a user interface informs the supervisory user of the location of the subordinate user based on the stored location information. At least one of the storing and/or the informing are based on the parental control.

Abstract: An online identity may selectively control perceptibility of incoming sounds associated with electronic messages between online identities (FIG. 4, 400). A first online identity is provided with two or more sound control options to selectively control rendering of one or more sounds associated with electronic messaging to the first online identity from a second online identity, and two or more control sound options to selectively control rendering of one or more sounds associated with electronic messaging to the first online identity from a third online identity (405). The selected sound control options associated with electronic messaging from at least one of the online identities are stored (410) and one or more sounds from at least one of the second online identity or the third online identity are received (415). The perceptibility of sound to the first online identity is selectively controlled in accordance with a selected sound control option from the first online identity (420).
