Hi BozMo.  Thanks for your efforts.  The user has made 6 edits to the article today  all of which are to add back the link, one of which was adding after you reverted.  An anon IP was adding the link yesterday and was constantly reverted, I presume it's the same user.   I don't believe the editor is engaging in good faith editing anymore.  S/he does not address any of the issues about the link on the talk page and seems only interested attempting to wikilawyer it into the article. (And no, I'm not an admin - quite happy leaving all that fire you brave folks ).   Siobhan Hansa
