The monthly post
A new set in your inbox
One or two emails a month, each with a printable puzzle in it, plus one set a month that isn’t on this site at all.
I’ll email you once to confirm it’s really you — that’s my record of your consent, which Canadian anti-spam law requires me to keep. The unsubscribe link is at the bottom of every email after that and it works the first time you click it. I use a company called Kit to send the emails, which means they store your address.
