    I'll admit to only doing half my job as I saw the following one elsewhere. It actually came up and was solved.

    Note: proposed rule-change carried by popular demand of 100% of voters in the relevant poll, now closed (1 of 1, (and no, it wasn't me)).

    Henceforth let it be hereby gently requested: Please do not post an impossible target.
