On December 14, 2012  all public chat rooms of Yahoo  Messenger have been shut down as part of a series of features being changed. While some user agree with the move, a majority of users of Yahoo chat are confuse and have unleashed their rage on on line forums.

We have decided to discontinue several Yahoo product features. This will enable us to refocus our efforts on modernizing our core Yahoo! products experiences and of course, create new ones  Yahoo had said in a web post earlier this month.

Yahoo has stopped some of the most popular products features and services that include Yahoo! Messenger public chat rooms and messenger Pingbox. As per the new changes, Pingbox will no longer be available on Yahoo Messenger and the company will assist users to uninstall Pingbox from blogs or social networks. Besides, Yahoo Messenger is no longer interoperable with Microsoft Windows Live messenger since yesterday.
