Well of course we do! But despite our omniscience, we are far too busy to answer all your questions. In fact, we are too hosed to answer any questions not directly relevant to those web pages we maintain. For questions about MIT, we suggest you check the the official MIT home page or search MIT web pages. If you have a question about a particular user's page, please ask that user and not us. For questions about life, the universe, and everything else, we suggest you simply don't panic.
