In this post @MitchWheat commented with a link to his blog, exposing some useful content to the OP.
I thought that this content would make a good answer and no answer with that content seemed to be forthcoming. So, I plagiarised from the blog and made it into an answer. I was clear that I had done that and also clear that I would remove and upvote if an answer from the author was forthcoming.
My answer drew a couple of downvotes and I feel kind of dirty for writing it but, Is it the way SO should be used?
Should I delete the answer or leave it as it improves the content on SO.
EDIT
Given the legal situation, I've deleted my answer. Not because I think I might have to go to court but, because copyright law has presumably developed to arbritrate in situations like this. Perhaps, my perception is naive...
EDIT 2
And now, post edit, its back.
