all the subscriptions are explained in the welcome post. if you're new to outside the box puzzles, be sure to give that a look.
to subscribe, click here (or on "subscribe" in the sidebar). be sure to pick a year 5 subscription (end date august 31, 2020) if that's what you want. you can also still get the year 4 puzzles (and if you really want previous years' puzzles, drop me a line).
i'll be traveling (to lollapuzzoola!) this weekend, but i should still be able to process subscriptions once or twice a day. if you subscribe and don't get a confirmation email within 24 hours, shoot me a message by email or on fb/twitter.
edit 8/20/19, 10:30 am: google has imposed a limit of 100 people i can add per day. don't worry, i haven't lost any of the information, but i won't be able to process some subscriptions until a day later.
