Mrrzy IS my real name. I've used it since I was a child. It may not be the name on my passport but that isn't the name I use. However, in assuming that nobody at the mudcat actually knew me first (turned out not to be the case) I figured it was as good as being anonymous... but when I needed anonymity I posted as Guest, Temporarily Anonymous, as it was germane to the discussion I was starting that it be known I *was* a mudcatter, just not WHICH one I was right then.
(Oops, I just gave it away, didn't I!)
