This is very sad news. I knew Andy slightly in the real world. We lived in the same area and he participated in the local forum that I police. He was noted for being a voice of sanity on there.
I met him a few times at the local exhibition, but the first time was when I bought his ladders off him and he revealed both his identities to me, the ladders having been advertised on the forum. The ladders were superfluous, as they were moving to a bungalow. The ladders were immaculate, as was his way with most things.
His last post on our other forum was on March 10th, thanking me for the 'birthday cake' I had posted for his 62nd birthday.
He was last on there on March 14th, but he was never a prolific poster (67 in 12 years) and absences of a few weeks weren't unusual.
I will miss him via both forums and in the real world.
