Google Talk, an Instant Messenger from Google, allows you to make voice calls and transfer files, Instant message friends, family, and business contacts.
You can even add the Google Talk Gadget to your webpage or blog.
Google Talk is a Windows application for Voice over IP and instant messaging, offered by Google. The first beta version of the program was released on August 24, 2005.
The Google Talk client is currently only available for Windows 2000, XP, Server 2003, and Windows Vista. Google reports that they are working on adding new features such as supporting SIP in a future release, which would broaden the user-base for the program.
Currently Google Talk doesn't have anywhere near as many users as other IM systems such as MSN and Yahoo, however its clean, simple interface and voice talk features make it a good choice and it is steadily growing in popularity.
Google Talk Client Features Include:
Offline messaging allows users to send messages to their contacts, even if they are not signed in. They will receive the messages when they next go online even if the user who has sent it is offline.
Google Talk is free and you can download it from www.google.com/talk/index.html
