A computer communication system that allows a user to conveniently display the most recent received messages associated with another user, and to directly initiate composition of a reply to a selected one of those displayed messages. When the user selects the disclosed “Reply to Most Recent” user interface element, a user name entry user interface object is generated that allows the user to specify the name of another user. A reply message user interface object is generated directly to the user interface, such that the reply message user interface object includes a message composition window that is automatically loaded with content from a most recent message from the specified user, and recipients for the reply message are loaded from that most recent message.
