How do you chat on Yahoo chat?

You go to contacts (or look on the left side of your screen UNDER contacts) and if anyone is on line you just click their name, another tab will appear and chat will start.

Yes. It comes with a default messenger but you can download better ones.

All you need to do is go to your contacts and click on the person you want to chat with and then it says invite to chat, then u click it.

Click on the contact you want to chat with, and click their messenger address. You can then chat.

You have to let it save a cookie on your computer. Enable cookies for this web site. This is usually why my wife cant get on. The stupid firewall. Good luck.
