Actually that came about because of some friends a long time ago. We all got in this habit of calling each other by our first name but backwards... so I was Neb. When I first trying to come up with a name for an email address I thought back to that. Believe it or not Kcid was already taken, so I decided to throw on "mil" since it's one of the many acronyms for my job. And it's just something I've used for my email and forums for a very long time now.
The constant joke around my shop is "D1ck, why are you such a d1ck?" In which case I have a name to live up to.
It's hard work being a professional at it. LOL
