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.
to subscribe, click here (or on "subscribe" in the sidebar). be sure to pick a year 6 subscription (end date august 31, 2021) if that's what you want. you can also still get the year 5 puzzles (and if you really want previous years' puzzles, drop me a line).
i'm bumping 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 right away. i'm keeping track of all the subscriptions that come in, and i'll add everybody in the coming days. 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.
