I decided against an alias, obviously, and chose to formally link my online life with my professional one. One odd thing is that I have never once been called "J.W." in casual life... I am Jason to everyone I know and that is how I introduce myself, and yet I chose J.W. as my my nome de plume and here we are.
The middle initial stands for Wingfield btw. Weren't expecting that one, were you?
Over the years I've gone by Racer X, AhhhFresh, and Mr. Sparkle... so those who have heard such names... 'tis me, for better or worse.
