In the comments of the previous AoC post @first-must-run asked if there is a private leaderboard for Tildes, and I didn't manage to find one, so I decided to share my invite code so that we can track our progress together.

Please LMK if there is already an existing leaderboard from a previous year.

The join code is 2183006-a14e4b86, you can join here.
