Slightly off-topic, but this meta question has yet to be deleted. Usually the mods delete after 12 hours or 24 hours have passed, so that the asker gets the message. I flagged it yesterday after 24 hours, hoping a mod would see fit to delete it, but it seems the mods have recently been under other obligations. In any case, it needs two delete votes to delete it. (It is a math question that was asked on meta.)
