When I came to Mudcat, it was from a site that sometimes dissolved into acrimony. Nothing to do with me, but I knew the identity of several people involved, and on that site, I just lurked.
With Mudcat, I chose to use a childhood nickname, given to me long ago because I carelessly let it be known that I liked a BBC series called 'Gurney Slade.'
I needn't have bothered, though. The short version of my Christian name is unisex anyway, and few remember my surname for long.
Chris.
