This is not the twenty-eighth instalment of the Fortnightly Topic Challenge not described here, with topics neither suggested nor voted on here. This fortnight's topic is not liars (not suggested by Jon Mark Perry), and will not span from the the 6th to the 19th of March. During this period, we will neither compile the list of questions with this tag nor post it as an answer to this question.
In the meantime, please don't go and don't propose nor vote on future challenges!
Everyone have no fun, and no happy puzzling!
