This is a two-parter, inspired by my curiosity.
First part is, how did you come up with your username? What's the story behind it? I guess, what's your origin story?
Second question, I've noticed a lot of us repeat character names. Do you? How did you choose it? How do you choose character names, in general? What inspires you?
I think most people know my username used to be vulgarkitten (I've heard some people think that's supposed to be a secret - it's not). I got it from an ex boyfriend IRL when I was trying to come up with something funny. He told me I should just pick two things I liked and smash them together. Thus, swearing and cats.
I changed my username to Hella to reflect moving away from that place in my life and back to what felt better to me. Hella is a spin on my minecraft username and what all my SMP friends call me, and have called me for 10+ years. For me, it's just a happier, better fit.
As for MU character names, I think the one I'm most (in)famous for is Catriona. I used it for years and years on Road to Amber, and then again on The Reach after the previous player gave it up. I chose it because I think it's a pretty name, simple as that. Also, I love that it shortens to 'Cat'. I'm a big fan of names that have convenient short forms (see: Monique 'Mo'). I think, though, that Catriona was the only name I ever reused a bunch across multiple MUs. The others have just been names that I thought were pretty and inspired me to build characters around them.
That's my story. What's yours?
