People who have yahoo id, msn id, aol id , icq id, can use it together on one messenger window i.e indiatimes messenger basically its for the chatter box wiz . who are always online . Its more of other messengers then itself .If you have tried yahoo or msn its similar to them only advantage is that you can club together you messengers and log into one messenger ( if you have registered in all ). but for a normal chat ...go for yahoo and for personal chats go for msn...
