Copyright Thanks for pointing out the too long quote I think you are right it potentially represents a copyright violation I have been using a few long quotes in my edits recently and I will review them all over the next few days rewriting or shortening them or whatever seems appropriate My only excuse is that I have been in physical pain while writing I can only do short bursts on the computer at the moment and the temptation just to quote someone rather than trying to rewrite what is already well written has been too great So I am indebted to you for reminding me of what I have been doing Many thanks and thanks for all the good work you have been putting into these articles
