Note to self: Do not tell your convention web site to publish instructions that say, "To do X, see the printed instructions downloadable from this page" and then, in the printed instructions PDF, write "To do X, see the instructions on the web page." Fortunately, someone wrote to me to tell me that I'd written a circular reference into the page the posted today, and I've submitted an update to the webmaster, but it's still annoying to have done it in the first place.
