Yahoo! Messenger 8.0.0.508 Beta

Use Yahoo! Messenger to call and talk over the Internet just like you're on the phone. All you need is a headset, or a microphone and speakers. It's that easy - just click the Call button. If no one's there, leave a voicemail!

You can also get much better sound quality than regular phone lines. Try it out - you and your friends will really hear a difference.

Find, add, share friends... It's easier than ever to add and invite friends to Messenger. You can even send your contact information to a friend's Address Book.
