Abstract: A server is configured to provide a service that manages access to communication sessions supported by at least one communication service and to which user devices connect. The service assigns to users registered with the service respective communication identifiers that the users, and unregistered users of the service, use to access the communication sessions via user devices. The service maps each communication identifier to a list of communication sessions, if any, in which the respective user is currently participating and/or is scheduled to participate. The service receives from a user device a join request from a requester. The join request indicates a particular communication identifier of a particular user registered with the service and a requester identifier. The service connects the user device to a communication session, if any, based on the particular communication identifier and the requester identifier.

Abstract: A system for evaluating network users comprises one or more processors communicatively coupled to one or more memories operable to receive, over a network comprising a plurality of network users, electronic first user content generated by a first user, provide the first user content over the network to a second user, receive, over the network, a second user response to the first user content generated by the second user, determine a second user response delay time for the second user response, wherein the second user response delay time is associated with the amount of time between when the first user content was provided over the network and when the second user response was received, and generate a first list of network users that have responded to first user content, wherein the first list is organized based at least in part on the second user response delay time.
