I used yahoo messenger for almost eight months and I have had a great experience with this messenger. It is very much user friendly and we do have option to join from various chat groups and we can chat with all out friends and relatives.
Even, so many smileys are there, we just need to choose and buzz option is also present in yahoo messenger. It is one of my favourite messenger and it provides great features and nice functions. It is very easy to install and doesnt take much time for installation. The service and support is pretty nice and overall it is good.
