Right, that's the one. I'm no Yvain, but I do have a dozen or so post drafts which I think would be relevant, but they will probably never be completed because of the effort required for "careful referencing / airtight reasoning (as opposed to a sketch of something which isn't exactly true but points to the truth.) " On the other hand, I see sloppy posts in Discussion all the time, and I don't want to post stuff like that, so I am not sure what to do about it.
