Lots of people seem to ask me, so I'll share the explanation of my name.
My father was a technology and gaming nut in his younger years; he was much akin to how I and many others are now. His Internet name was Zahldoom. He apparently just came up with it one day, as far as I can remember.
I eventually took the 'Zahl' and tacked on 'dar', because I wanted to keep the 'Zahl', and 'dar' sounded nice with it.
If I hadn't finally done that, I'd still be known as '6894521,' my original Runescape username (which I eventually dumped) and past home phone number. (I mixed up the username and password categories in the account creation. I was in 4th grade, cut me some slack.) I really do pity the poor soul who actually had that phone number...
[collapse='Bonus!']Also, before anyone asks: no, Zahldar is not a Power Rangers villain. Seriously. How many times am I going to be asked/told that is sounds like that?
Also, interestingly, Zahl means 'number' or 'figure' in German. I had no idea about that.
