When written in all caps, referring to Darren Semotiuk of Edmonton, Alberta, Canada. Self-proclaimed nickname due to incessant obsessive nature of automating things (on the computer), with scripts, DOS BAT files, etc.
[Even received a "Batman" T-Shirt from a friend because of the nickname. Yeah, I'm a propellerhead. But I won't include my email or a URL because you never know what kind of response that might bring.]
