I agree that for 'some' subjects it doesn't really matter, but for a lot of the queries,
and asking for assistance, it really does.
I've seen multiple times where a question has been asked, and the person replying
has not only given a reasonable answer, but has also offered to pop round and help
with the problem (such is the quality, and generosity, of the membership on RMweb)
only to discover that the OP is at the other end of the country, or even further!
And yes, I've heard the feeble argument that they are worried about security issues, etc.
but I'm not advocating postcode, or anything like that. I've chosen to put my home town,
the county would have been adequate, for non-UK residents just the country would do.
Finally, my apologies for hi-jacking your thread, I'll put away my soap-box now, good luck
with the boards/layout. My opinion is that whatever you use, it is given a few good coats
of stain/varnish/seal to protect it from humidity, insects, mould, or just the ravages of time!
