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.
It's koine Greek for "Father of Truth." But, more specifically, my daughter is named Aletheia, so basically, take it to mean Aletheia's dad. Also, I only got a B in Greek, so that may not be exactly right, but close enough.
