I'm a bit shy about this article amongst hardened Zopistas as it shows that I'm only just reaching the steep part of the learning cliff having wandered through the gentler foothills over the last year. The article was written at the end of 1999 and has yet to appear in print (and is dating rapidly). So I'm casting etiquette aside and broadcasting its whereabouts generally. It will not give Zopistas any new insights but it might help them in the cause of persuading others on board (which was my motivation for writing the article in the first place).
