What's the deal with your nickname? How did you get it? If your nickname is self-explanatory, then tell everyone when you first started using the internet, and what was the first thing that made you say "wow, this isn't just a place for freaks after all?" Was it a website? Was it an email from a long-lost friend? Go on, spill it.
About seven years ago I was working for an ISP, and was given web space and allowed a domain on the company dime. After a night, on the clock (a factor in my surprisingly quick dismissal), of looking up domain names, I turned to a Latin-English word translator and came up with "griphus", which translates to either 'riddle' or 'enigma'. The name stuck, especially as 'griph' goes over pretty well as a general nickname.
