Many people have used or are still using an online chat service of
some kind. This free method of communication has proved incredibly popular due to it's simplicity and is especially useful if you have
friends and family abroad.. Even social networking
sites such as Facebook incorporate a chat facility amongst online
friends. The trouble is, communicating in this way for any length of time can quickly become
tedious, and there's no easy way of communicating with multiple users
simultaneously. 20 Feb 2010
