The Krazydad Discord server is a new place where you can talk to me, and meet other people who are interested in puzzles. You can report problems or mistakes with this website, suggest new features or new puzzles, get periodic announcements from me, or discuss the theory-of-puzzles and other deep thoughts. Maybe I'll see you there!

Lately, it seems a lot of my incoming puzzle correspondence is ending up in the spam folder. Ugh, thanks a lot Google! If you'd like to guarantee that your important message doesn't end up in the spam folder, just include the magic word TARADIDDLE somewhere in your message. I have instructed Jeeves 1000, my personal correspondence robot, to pluck emails containing this secret word out of my spam folder, where they might otherwise languish in obscurity. Thanks again!
