I am using yahoo messenger for years. I am fully satisfiied with this messenger. Other messengers like msn and aol went for paid service while yahoo provides free service. Yahoo Messenger is easy and simple to use. We can also use our GSM mobile for chatting.
In the new version of yahoo messenger we can send flirts to whom we are talking for and very good privacy facilities available.
Different members can be given different status.ie one can be made visible an another can be made invisible at the same time.
When we are signing out from the yahoo messenger we can automatically turn online to our mobile. We will get messages through our mobile.
Disadvantage is that only 2 yahoo messages can be send continously on the mobile , further text can be sent only if the person replies and the message through the mobile will cost Rs 3 per message which is very high.....new version has lots of graphics , but takes lot of time to load.
It will give alert messages ..
No service for archives if we are working on different computers.
Better video quality( web cam) , but poor sound quality(voice chat)
