and then you have to submit an e-mail. I think this is somewhat a matter of semantics. I deal with a lot of authors, and most of them have a web site for a book, or for themselves, where there is a Contact page, or Appearance Request page, where you e-mail them if you want a signed copy of their book, or if you want to set up an appearance by them, or if you just want to ask them a question. It's handled via the web site, so that they are not posting their e-mail address on a public web site.
