Good article, @raymondbruce. You have a few spots which need some editing for correct English language usage. I don't have time to give you the suggestions for improvement right now, but will come back later if I have time to, and suggest anything that you have not already discovered.
For now I have upvoted and resteemed this post as my daily post promotion for people whom I have previously curated.
Cheers!
@mitneb
I'll go through it again
Thanks for your help
