This is definitely a most handy tool to have around..MAn you can chat online with your friends.You can either have voice chat, which is not always clear or you can exercise your fingers a bit ( more advantage--improves hand eye coordination) and type out ur messages. But what I am saying here is that, you can say what you want to your friends in India or Abroad, whenever you r online. Isnt this fast or what?. Also the messenger has undergone a lot of changes, and the newer ones sport so many features..The smileys are a cool way of expressing ur feelings too.And the advantage yahoo has over msn, is that you can log on in the invisible mode , and make ur presence known only if you want to .That is cool.
And there is hardly a problem of connectivity as in Hotmail
