The forum itself is possibly too organic, IMO. That's why I like the approach of separating off the threads which Jeri showed us. We could at least keep on-topic posting only there, making the thankless task of the editor(s) manageable.

And Malcolm, I'm not sure if you are suggesting that the discussion of the sources should be deleted once clinical editing begins? Or are you suggesting a list of sources, with the consensus as to the veracity of source information, be summarised and retained in the threads?

I would favor that, but not eliminating dodgy sources altogether.
