See ' Instant Messaging' for more details, or refer to the ICQ Web site at. When someone you know logs on, you can instantly initiate a chat session send messages exchange files or launch peer-to-peer applications such as games, Internet telephone calls, and videoconferences.

When you log on, ICQ automatically detects the Internet connection, announces your presence to the Internet community, and alerts you when friends sign on or off. ICQ uses this list to find your friends for you. Once you've registered, you can compile a selected list of friends and associates. At the time of registration, you receive a unique ICQ number and you can optionally provide personal information that allows other ICQ users to recognize you when you log on. To participate in ICQ, you register with an ICQ server, which is connected to a broad network of servers spanning the Internet. ICQ is an instant messaging system that informs users when someone they know is online and lets them instantly chat with one another.
