That question is either a joke or the person got my email address from a friend. You be the judge. I may or may not answer this depending on whether or not I feel it is sincere. The webmaster lost your message. I have done this quite a few times myself.
Some webmasters get a lot of mail.
Like I mentioned earlier, your message can get passed over while the webmaster is sorting out the mail. Try again in a couple of days and see if they catch it this time around. As webmasters, we need to be sure we do the best we can with the email part of the job. Try to respond in a polite manner if possible. Sometimes, this isn't possible, I know.
