      As we did for the last two years, I've set up a temporary sub-group that we can use for this year's Advent of Code at ~comp.advent_of_code

      I moved all the Day 1 solutions that were posted in the thread that @JRandomHacker posted into a dedicated post for the Day 1 problem, and I've set up scheduled posts to happen automatically as each day's puzzle unlocks.

      I also automatically subscribed everyone that voted on that original topic, as well as everyone that posted a comment in any of the previous years' topics, but nobody else. So if you're interested in participating in Advent of Code or discussing it, please subscribe to the sub-group. Posts from the sub-group won't be shown to logged-out users by default either, so any logged-out users that want to observe will need to visit the sub-group directly (or you're welcome to email me and request an invite so you can register and subscribe).
