I see you have changed the section page, and it is fine by me.
However, I suggest using this formula for the contextual pages you are removing, to avoid competition with single entry pages with the same name, so, I propose the following formula: 'Introduction to Sectionname in a P2P Perspective', example, Introduction_to_Governance_from_a_P2P_Perspective
On second thoughts -- yes, the idea of an "Introduction" name is good, but I'm not so sure about the reason. If there is a page of that name -- "Governance" -- then surely we ought to have it as the introduction, or redirect it to the introduction? In this case I've redirected it. Change that if you think differently! Simon Grant (talk) 09:28, 11 February 2017 (UTC)
