FWIW, I agree with the above, except for having strong reservations about:
it may be appropriate to transfer ownership of the node to pedagogues while adding brief content to the top of the node noting (and thanking) the original author and explaining why ownership was changed.
I'm not able to think of a situation where creating a new node owned by
pedagogues wouldn't be better. Though that causes a problem since you can't have two tutorials with the same title, and the existing title may be the ideal one. Does the original get (
author) appended? Does it get "downgraded" to a meditation? I don't see a perfect solution.
