“Netscape Communicator 4.51, our highest quality browser to date,

AOL Instant Messenger 2.0 with Buddy Chat allows users to send real time

as a group. Additional features include Search, to help individuals use
the Web and locate friends, family and business associates by name,
email address or common interest; Neighborhood Watch, privacy controls
for sending private messages while choosing who can “see you” online and
one-click buttons to connect users to other Netscape Netcenter services.

Quotes Anywhere is a new capability of Smart Browsing that provides
users with up-to-date stock prices by simply typing the word “quote”,
followed by a ticker symbol. If a user has a personal finance portfolio
hosted on Netscape Netcenter, either on the Personal Finance Channel or
