For example, this one. Clearly it doesn't fit well into our website, and the best think is to ask the user to split them to separate questions.
What if the poster isn't responding? Other members will be posting answer as we wait, while the question is still not changed. Should we take the liberty to edit the post to include only one question? Should we post the rest as separate questions? Or should we close it temporarily (to prevent answers), and promise to reopen it when it conforms to our standard? Or just wait?
