Yahoo yahaven is yahoo software as yahoo messenger. You can login your any Yahoo ID in this software and can get all those works which you can take from Yahoo. But there is also much more options in this software then Yahoo. You will get mic lock option, id invisible checker option. I have used it from a long time and i have taken too much benefits and now it's the time for your to take works from this. I am sure that you people will like it too much as i liked.
