The highest level monks have the ability to move nodes between sections, if I am not mistaken. So presumably what should happen is that the node posted in the wrong section will be moved to the one where it should have been posted (the one posted in Q&A that has an involved answer, for example, will end up in SoPW) and then the duplicate can be weeded out. Or, the node posted to the wrong section can get deleted straight off the bat; and the note the considering monk posts should explain this : (arturo) double post to SoPW, Q&A. This system is, for obvious reasons, imperfect and error prone.

What this means is that the key to this one is, I think, noder education rather than more code.
