Will Shortz has sent back a whole bunch of my puzzle submissions, most of them not fitting the New York Times' strict criteria. He did, however, say yes to one puzzle that was sent to him way back in the summertime of last year. (Oddly, this same exact puzzle was first sent to Tim Parker over at USA Today and promptly rejected within a matter of days.) We will advise you when this, or the other puzzle Will bought last spring, are going to be on the schedule.
So, fellow puzzle constructors, don't give up hope. Your day will come!
