add real-time chat to your website. The Windows Live Messenger Web Toolkit is a new set of controls and libraries that let you chat with your Windows Live Messenger friends and other website visitors. This automatically adds a social element to your site, without having to transform your site into a social network.
To get started, developers can choose the level of customization by using the pre-built and skinnable Web Bar control, using the 16 modular UI Controls, or building the entire experience from the ground up using the Windows Live Messenger Library. But the easiest way to begin is to use this tool, which provides a step-by-step guide and sample code to get you started.
You can try it out now from dev.live.com/messenger.
