Well, it's a little involved, but not that much.
Back as a freshman in high school, low these many years ago, I was into Dungeons and Dragons. I was president, in fact, of our high school gaming club, at the time.
Well, as it happened... wait, I need to explain for those of you will not understand this.
In D&D, as it's called, you "roll up" characters. You roll a six-sided die (yes, there are more sided dice out there) to determine the "attributes" of your character. Which, in turn, determines the powers and skills of that character, in the game.
Well, I was, probably, a freshman in high school at the time. And I was sitting at my grandparent's kitchen table, rolling up a character for D&D. And, completely by chance, I rolled up a perfect wizard-mage. Which will mean nothing to those of you who never played, but... this was an honestly _very strong_ player in the game.
I knew I had honestly and truthfully rolled up a superb character to play. I needed a name.
And I looked over, to my right... and saw a box of Cheezits... yes, the snack cracker... that my grandpa so liked, on the kitchen counter.
Well, with a bit of fiddling with the name, that character became "Chizotz". And I took him to 38th level. Before I eventually... grew out of the game, for lack of a better term, and, basically, gave him, and the game, up and moved on.
But online, I am, from the beginning, Chizotz. My very first account, on Q-Link (if anyone can remember that, besides me) I was Chizotz. And I am, to this day.
I have had my name usurped a few times. A notable occasion ended up, unfortunately, with my "Chizotz" moniker posting porn... a lot of porn, unfortunately, before I could stop it... to various places, mostly usenet. That wasn't me, it was an identity thief. But if you search for it, you might still find it. Even though that was 10 years or more ago.
I got my name usurped because I was extremely active on the net, between 20+ and about 10 years ago, and I was a ripe target at the time. It isn't surprising that happened, in retrospect.
I was also into gaming, and actually wrote an online book, the "Unofficial WAD Designers' Handbook", on how to create your own Doom and Doom ][ levels. Maybe a few of you do remember that, if you were ever into gaming. Yep, that was me. I am, indeed, that Ron Allen/Chizotz.
I was very active on online forums, and usenet, and even had my own Windows help-desk site for awhile.
But my online activity has since been severely curtailed, about 10 years ago, by my own desire. These days I'm perfectly happy to just be the father of a 6, soon to be 7, year old, and have left all that behind me years ago, and don't miss it much.
Now I just haunt places that catch my fancy... such as smoking meats :)
So... there's your answer about how my screen name came about. You have an internet oldster in your midst, trying to learn how to smoke meat :)
