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.
I needed a nick for another site that could only be letters and had to be pronouncable (i have no idea why, but their site, their rules). After about 100 tries of coming up with stuff (ok it was 3), and being told username already exists. I just typed something semi random that met the rules ... forfor was what I typed, but another rule was the it had to be at least 7 letters ... so another f got added. Maybe some day I'll come up with some witty and cutting edge phrase that has forforf as an acronym. Until then its the boring truth.
