Question Author
Hi all - I now note that I have NO 'best answers' at all.
This is no surprise as I ask more questions than give answers.
However, because l'm such a softie, I'd like to give everybody a 'best answer'.
I would like to say though that there are a lot of knowledgeable people on this site with regard to technical & building queries and I do like to pick their brains!
I do like the odd chit-chat though..........
