Let's say an OP asks a bundle of questions all in one post, he gets politely guided to ask one question per post, he ignores the guidance, the correct number of days go by, and now I'm cleared to jump in with my edit hat on to fix his question.
Is it sufficient to select one good question out of the bunch, remove everything else, and leave it at that? With a comment to the OP explaining what I did, and encouraging him once more to write more posts with the rest of his material.
The alternative is, it is my responsibility, if I want to edit and fix his question, to create the additional questions FOR him.
