Login invisible in Adium?

Hello,

In Windows Live Messenger you can choose to login invisible. (so you can see your contacts, but your contacts can’t see that you’re online) A (reactively new) feature even allows you to send messages, even if you’re invisible.

Can this also be done in Adium. So that when I start Adium, my buddies can’t see me, but I am logged in.

It’s kind of complicated to explain this, but I hope you understand it.
