Google has launched an orkut “chat roster” that shows you all of your contacts who are signed into Google Talk, whether through orkut, Gmail, iGoogle or the Google Talk application. If you want to chat with any of them, all you have to do is click on their names directly within the roster. No matter where you go on orkut, the chat roster sits neatly on the left side of your orkut page. You can customize the size, organization, and look and feel by clicking on the ‘options’ tab. Of course, if you ever get tired of seeing who’s signed into chat, you can also minimize the roster (or sign out of chat entirely), with a single click.
