Tim, I have skimmed through that article, and I must say it's a privilege to even be asked to review it, So thank you very much. Alas, am a bit tied for time at the moment with stuff in the "real world" (yes, I think it still exists), so any review I offer will probably be for very tiny spelling mistakes and missing links (if there are even any at all, of course)! I know so little about Bax, that reading it will be a complete education.
