Hi Ian It seems that I cannot see your email address, but as I write this I can see mine, so perhaps that is when it is visible. So please contact me on firstname.lastname@example.org
I would be interested in your info and in particular any certificates. Just let me know how you choose to send it. Is there detail that I might have. I am much more rigorous now about sources and citations.
best wishes Penney
I reread my las p[osting after it was posted and apologise for the typing errors. Teach me not to read what I have written!
