Abstract: A computer program or method provides away messages from a first user to other users of a communications system, where the first user has grouped the other users into two or more groups. An interface is provided to the first user that displays representations of the other users in a manner that identifies how the first user has grouped the other users into the groups. The first user is able to select a selected group from the groups using the interface. The first user also is able to set a group away message for the selected group using the interface. The group away message is sent to a second user that has been grouped in the selected group when the second user attempts to communicate with the first user using the communications system and the first user is offline.

Abstract: An authorized client communication system seeking access to a host communication system may be identified by locating a memory segment within the client communication system that stores client software used to access the host computer system. The memory segment then is examined to determine whether the client software stored in the memory segment corresponds to client software for an official client communication, system. Communications from the client communication system are terminated when the client software in the memory segment is determined to diverge from software for an official client communication system.

Abstract: Managing instant messages may include receiving instant messages created by or on behalf of one or more message sources for delivery to an intended recipient. From among the received instant messages, qualifying instant messages may be identified that satisfy a capture rule, and two or more of the qualifying instant messages may be captured. The intended recipient may be informed of the captured instant messages unobtrusively, and also may be enabled to manage the captured instant messages.
