MSN Tests Web-Based IM Client "MSN has launched a beta version of a Web-based instant messaging client in five markets, including the United States.
The MSN Web Messenger beta, available here, runs on Windows 98, 2000, Me and XP. It supports Microsoft's Internet Explorer as well as alternative browsers. It supports IE 5.0 or later, Mozilla 1.6 or later and Netscape 7.0 or later.
Also, users are able to run the beta on Apple Computer Inc.'s Safari browser for Mac OS X, but MSN does not officially support it, the spokeswoman said."
