[Air-l] Help: Info. regarding history and evolution of MSN Messenger

Hello, Sorry for this interruption. Just stumbled upon your listing under search heading: History of Instant Messaging on Google, and thought you might be able to help. I'm trying to find information regarding the history and evolution of MSN Messenger (e.g., earliest version, features, and changes throughout its evolution) but haven't turned up much. Any feedback or leads would be welcomed and greatly appreciated. Thank you, in advance. Best, James Lau Microsoft Global Technical Engineering Center, Shanghai Communications Specialist
