Yahoo messenger 9.0 came with this new application called Pingbox among others. You can edit it first on the Yahoo Messenger page and then copy and paste the html to your blog, profile or website. It looks very handy and easy to use. The ones who will send you messeges through it will appear as Visitor 1, 2...an so on. I added it and will test it for a while to see how it is. You can read more about the new messenger and its new features on Yahoo Messenger Blog.
