I just noticed your edit summary mentioning me  I had nothing to do with that I did check the history and the diff does seem odd   it looks like your comment disappears in the course of a long reply of mine to multiple comments including yours And something odd happened yesterday as well   it looks as though both the tail end of my comment and one of yours were deleted by an anonymous IP and then mine put back Raymond arritt then put yours back While I frankly consider your comments and suggestions not exactly to be in the best interest of improving the article I find this odd deletion stuff more problematic in the context of other things going on Might I suggest that whoevers been doing this stop BC aka
