Inquiries by E-mail and Usenet

I sent an e-mail requesting some information, and never got a reply. Why not?

Most of the time, it is because you entered an invalid e-mail address. We do not (yet) have the ability to warn you about that ahead of time. Occasionally, software or computer problems cause e-mails to be lost in transit. Regardless of the reason, if you have not received a response from us within a week or two, please contact us again. The only messages we normally do not reply to are spam, frivolous messages, "keep up the good work" messages, and thank-you replies.
