I had to sneak it in as part of my last name, but yes. I was using GreenReaper way before I'd heard of the fandom. In a very real way, it is my name, and I would like people to be able to look me up under it.
There are far more people who know me as "GreenReaper" than as "Laurence", including virtually everyone I initially met online. My boss uses it, even. :-)
I should also be a first-page hit if you're logged in and search people for "furry", although I'm not sure if it's pushing my profile up just for me.
Alas, as much as I love to talk about myself, this is getting off-topic . . . so, anyone else noticed that FA is just about to pass submission ID 5,000,000?
