Good evening David,
Just got rid of some of my work backlog caused by the visitors, I did grab a quick look when they left mid-afternoon and there was a challenge up from Martin, but I didn't have time to follow it up and I guess that as there was nobody else about and no nibbles before he went for the weekend, he understandably removed it!!
I'm off home soon and will take up the hunt later, is yours a project or reality?
