Can you use KatsKorner or a variation on that for your Etsy shop?

Well, there are very few (three) Etsy shops with "KatsKorner" in their names... but I'd rather choose something else. Maybe I could change my Zazzle name instead?

(later)
I've changed the Zazzle name, and while I was doing that, I uploaded a banner, so thanks for prompting me to do that!
