Dear friends, now i am urgently need to use yahoo mail account to chat with one of my client. But i am not familiar with sending chat request and chatting through yahoo mail. Even after more than 2 hours of internet search, i couldn't find the details till, so that i came here. There are some guides which explain only about the older versions of yahoo mail. I urgently need your opinions especially who are using recent versions of yahoo ID. Thanks in advance.
