Welcome Allan to the forum. There is indeed a great deal of talent and knowledge kicking around herein. So don't hang back, if you don't know, ask, someone will know. And probably most importantly, there will be people reading this forum who will have the same or similar problem but who for whatever reason dare not/ do not know how to/cannot formulate the question to, ask for help and who will then enjoy and learn as well.
I'm in West Cumbria which is hardly local to South Wales. Indeed, West Cumbria is hardly local to anywhere, apart from the sheep that is.
Good luck, and enjoy.
Regards,
Peter G. Shaw
