Gracekrispy is a nickname I had once. I tend not to mention any other names of my family on boards bc it's a small world and if you know generally where I am and what I do.... Well, I don't trust a ton of people. My real first name is in my user name, but that's as far as I'm going.
I change avatars like I change clothes-- fairly frequently
. It's always a penguin, just like it's always me in my clothes. That's enough consistency for me. On my other board, I change to random (sometimes wild) avatars, but my name is well-known there, so it's all ok.
My name is a constant, but my "appearance" (avatar) does change.
