Abstract: A system for forcing e-mail addresses into the Bcc: field of transmitted messages in order to enforce user privacy. A user interface enables a user to indicate that their e-mail address is not to be included in a “To:” or “Cc:” field of an e-mail message from another user when the number of e-mail addresses contained in those fields exceeds a threshold size. The user's e-mail address and the associated threshold are stored for future reference when new messages are sent by the other user. Subsequently, when a new message is generated by the other user in which the number of e-mail addresses contained in the “To:” and/or “Cc:” field exceeds the threshold, then the disclosed system moves the user's e-mail address from the “To:” or “Cc:” field to the “Bcc:” field of the message before the message is transmitted to its recipients. Privacy messages may either be sent individually to specific users, or may be automatically generated as a result of a general privacy setting being indicated by the user.

Abstract: A system for flagging content in a chat session and providing enhancements in a transcript window. The system allows a user to set visible flags at the starting pointing of lines in the transcript area of the live chat window. Once one or more visual flags has been set in the transcript area, they are visually displayed in the transcript area visually indicating the lines they are associated with, and the live chat window is further modified to enable the user to navigate to the flags. When a flag is set, it is also added to a visually displayed list of such flags. The visually displayed flag list allows the user to select a flag and quickly navigate to a particular area within the chat transcript area that the user has deemed to be relatively significant. The flag list may be displayed at the top of the chat transcript within the transcript area itself, as a horizontal list of hot links, or in a new display region added to the live chat window, or in some other way.
