(CNN) - Mark Zuckerberg wants to hear from you through Facebook.
But it'll cost you.
For $100, you can send a message to the social networking chief's Facebook inbox.
The offer is part of a beta test for Facebook's new revenue stream.
Last month, Facebook said it would begin testing paid messages, but didn't disclose how much they would cost.
Under the current Facebook system, messages to people who are not in your network go to a mailbox that most users don't know exists.
Facebook said it is using the extreme price point as another type of spam filter.
The company hopes that messaging people you don't know would be a privilege worth paying for.
