Use Facebook Chat without opening Facebook.com

ChitChat – If Facebook were to develop a standalone messenger on the lines of Yahoo! or Google Talk, it might look something like ChitChat.
ChitChat is a Windows-only desktop client for Facebook that provides a tabbed window to make it easy for you to talk to may friends at once. It will also show notifications in the tray when your friends go online or when they have signed out. The application is in RC stage so expect a few bugs.
