I originally created this list in Nov 2015.
I want to thank those who noticed my errors and helped me correct them.
This post was in the middle of a longer thread and wasn't convenient to find, but I did keep it up to date.
The original thread was started by bschwartz.
There is a second sticky in this Forum Topic that has all
User Submitted puzzles, which are also worth points, open to all, and eternal.
Patrick, thank you for making this a sticky. It is much easier to find.

Newsletter PuzzlesIn the early autumn of 2019, Patrick invited subscribers to sign up for a newsletter. That newsletter would arrive at random times, and have puzzles. It is one of the perks of being a subscriber.
Click on SUBSCRIBER, in the upper left corner of any puzzle page, and you should be able to subscribe to the newsletter.
Patrick has created a post that has links to the first five newsletters.

Turning in this puzzle will give a person the EVEREST achievement, along with 25 points.
