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.
Come to think of it, "Zeph" is a foreshortened version of another nickname I tend to use online. Just sounds friendly to me for some reason. As for when I realized the internet was something special, the first things I specifically remember getting hooked on included the non-graphic version of "Find the spam" and, eh, MUDS and X-Men fanfiction ... coz I'm cool like that ... yeah =P
