I had been using a "Fred327" type name until I found my particular "Fred327" had already been taken on Ebay. my second choice was also taken, so I ended up with anoter "Fred327" name on Ebay but was not happy with it, so when I signed up for Mudcat I decided on something else. Since my wife refers to my recorder playing as "Tootling", I chose Tootler. I have since used Tootler for other music forums I have signed up to.
