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.
Last name = Leach. Childhood nickname = Leachie. First initial = L.
(Note: Both my husband and I are now a hyphenate, so we're "Leach-Steffens".)
