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. none of the prices or plans have changed from previous years—for the seventh year in a row, i've not found it necessary to raise prices. that's because the number of subscribers has steadily grown, and my basic expenses haven't. (i have steadily raised the payment rates for variety puzzle constructors who contribute to the site, though!)
to subscribe, click here (or on "subscribe" in the sidebar). be sure to pick a year 7 subscription (end date august 31, 2022), assuming you want to subscribe to the coming year rather than the year that's ending now. but you can still get the year 6 puzzles as a bundle (and if you really want previous years' puzzles, those can still be had, too; drop me a line).
in the late-august period, i'm often up against the daily limit of subscribers that google groups will let me add, so don't be alarmed if you don't get a confirmation email from me right away. i'm keeping track of all the subscriptions that come in, and i'll add everybody in order. if you don't hear back within 48 hours of subscribing, do let me know and i'll check to make sure nobody slips through the cracks.
see you in year 7!
