It was also the first major IM client to feature BUZZing and music-status.
Another recently added feature is customized avatars.
Yahoo also offers PC-PC, PC-Phone and Phone-to-PC service, file transfers, webcam hosting, text messaging service, and chat rooms in various categories.
Yahoo Messenger was originally launched under the name Yahoo! In addition to instant messaging features similar to those offered by ICQ, it also offers (on Microsoft Windows) features such as: IMVironments (customizing the look of Instant Message windows, some of which include authorized themes of famous cartoons such as Garfield or Dilbert), address-book integration and Custom Status Messages.
As of March 27, 2016, the only supported clients are the Android, i OS and web browser clients.
The legacy Windows, Mac, Linux and Solaris clients are not supported anymore, and their servers will begin shutting down on August 5, 2016, It turned out that the servers for the legacy clients were finally shut down sometime between the mid-morning & early afternoon hours east coast time on September 1, 2016, resulting in the legacy desktop clients no longer being able to access their buddy/contact lists.
Yahoo Messenger is provided free of charge and can be downloaded and used with a generic "Yahoo ID" which also allows access to other Yahoo services, such as Yahoo Mail, where users can be automatically notified when they receive new email.
thank you As far as Yahoo is concerned there is no sex chat in Yahoo messenger and even in chatrooms you can find maybe in others website of having what you are looking for.
Hope it will make you understand of what you asked. I have been trying to find a good online chat room for hot sex chats but all the time I find only spams and bots.
