Are you one of those Windows live users? Would you like to chat online with visitors to your blog or website, using Windows Live Messenger? Without your friend/visitor having to install messenger and add your email, they can simply send you an instant message right from your blog/website pages, like the one below.
You can either show a messenger status icon or even the complete messaging windows to enable the public to send you an instant message. Online IM allows even a visitor without Messenger ID to send you an anonymous message.
