I've sent Randy a couple of e-mails over the last years and never received a reply. I just figured that he had a pretty heavy volume of mail to look at and just moved on.
I do however, suggest that he implement an autoresponder of some kind so that people know what to expect when they send him an e-mail. Randy's public personna seems to indicate he wants input from each and every one of us, but that is clearly not possible given the size of the board.
