Yes, it is fun - both to have your own and to discover others. I
feel no need to hide my real-world identity, but am glad for the
diversion provided by these playful monickers.
My screen name with Yahoo (GraybeardR) began when I registered to
play their games - mainly a challenging board game called Reversi
(Othello), which comes naturally to a chess-player of some 70 years
experience. And 'Cock o' the Trail' follows from long hiking
experience and - again - about 70 years of raising plain and fancy
poultry.
As they say, "you are what you eat" . . .
