Address Book: IS YOUR CONTACT AVAILABLE FOR CHATTING?

If you're getting ready to send somebody an email, wouldn't it be better to get an answer right away, rather than waiting for them to reply to your email? Address Book can help, because when you go to a contact to get their email address, if they're using iChat and they're available for chatting, you'll see a little green dot next to their picture (consider that a green light for chattingthey're online, and available!). All you have to do now is click directly on that little green circle to bring iChat to the front, and then you can ask them if they will accept a chat from you. They probably won't, but that's an entirely different issue.
