Hey, where did your LiveJournal username come from? (If you have numbers or underscores or, G-d forbid, extra x's used for spaces in your name, don't count those. Only the words.)
It's my real name!
It's (based on) a real-life nickname that I decided to use on LiveJournal too.
It's a name I used to only use online, but now people call me that in person too.
It's a handle that I use online frequently, but never in person.
It's a LiveJournal-only name for me.
