about messenger 11 it really really needs to be redone cause a lot of people are having the problems of not being able to private message with anyone unless they add them to there friends list.and that is not a good thing to do adding people you just start talking to , ive uninstalled the messenger 11 and went back to the messenger 10
i highly suggest if you are using yahoo messenger to go into chat room you should start using a chat client instead and the best one that is available now is called ysupra they cannot boot ysupra
the link for ysupra is http://www.ysupra.com
