Martin, unfortunately that is the nature of Homo sapiens.I have encountered a lot of it on this forum,people like John Adams taking the piss out of my name[ Dick Miles]which was just puerile,and others, of which I will be gentlemanly and not mention.
on the other hand,There are plenty of decent people on this forum the most rewarding threads[IMO]are those about instrument techniques,from which I have learned something,also folk radio programmes[I might otherwise have missed].
And Jim Carrolls contributions,from which I have learned a lot about Walter Pardon.
