Windows Live Messenger is well designed to help you chat with one or more friends online for fun, work, or both with voice calling, video conference, gaming, and mailing functions. The core of the program has not changed much from the previous versions, but adds a great array of new features that the user can surely benefit from.  

• Call your friends' PC (free), mobile or landline phones. 
• Calls require a microphone and speakers or a headset and broadband connection.
• Make calls for less than $.02 a minute to most places around the world with Verizon Web Calling. 
• Start a video conversation within minutes with a webcam. Drop in photos and other stuff for friends in a Sharing Folder, as many as your computer can handle. 
• With Windows Live Messenger you can now connect with your Yahoo! IM contacts.
