"Hi Mel, I saw your request for assistance on the Papakura page. It is an intriguing offer, I thought about it seriously for a couple of days, but ultimately decided that I have too many fish to fry at the moment. There are others on the Papakura page who are much better qualified than me, and they will likely be in touch. There are opportunities for collaboration in the future, however, so keep in touch via the Papakura group page. M.R.
