I share puzzlehunt-style puzzles on the Puzzling Stack Exchange under two accounts. Here are some of the highlights:
days are determined (Note: once you think you’ve finished the first part, click here for the second part.)
Septahunt, made with two friends (sus1d1p and zimodo) for a another friend.
Diagramless Minis, a puzzle for David Millar’s Black-Out Friday puzzle set.
