Whenever I see a strictly-EE-question posted on StackOverflow I suggest that the asker repost it here in our EE beta SE.
Great that the asker gets a quicker answer, but now we have needless duplicate content.
When I see posts like this what is the best way to handle, should I:
Ask the submitter to ask a new question and to delete their old one?
Ask the submitter to request that a moderator move their question?
Ask the submitter to add a link to their new question?
Myself ask that a moderator move the question?
Or something else?
