I'd swear at you in Welsh but I fear I may wear-out my 'l', 'e', and 'u' keys ;)
Thanks all - appreciate that some of my enthusiasm came through, though the previous poster had a point about the sheer density of my excitement so I toned it down a little while making a few corrections, clarifications, and improvements in the update I posted this afternoon.
