Latest Version of Msn is fantastic according to me. It`s main advantage is that if you have a hotmail id you need not sign up for a new id. It is easily available on Msn site and gets downloaded on the computer very fast. After you download it on your computer you give in your hotmail id and your hotmail password and sign in.
After signing the second best advantage is that a small message menu pops up from below your computer which tells you if you have received any new messages or not. Secondly it helps me to know if my friends are online or not. If my friend is online my friend is highlighted in green to tell me that he is available for chat. Also with latest version of Msn one can have a voice chat with your far away friend.
Apart from all these advantages, conferencing with your friend is also possible that is three to four friends can talk at the same time in one chat room. It`s special features are you can insert images while you are chatting. You insert a laughing face with :D or send your friend a flower with (f) or a heart with (L).
And lastly when you have finished chat just click on sign out button and you will be out of your chat room.
So in the end I would say that it is a great service for chatting online with your friends in a very simple way.
