I would, but I don't have a premium account. Plus, I've already made the account that I would have used if I wasn't already kind of invested in this one, so even if I were to change it, it would not work because even if I'd changed the other account's name, once you've taken a name at some point no one may take it again.
Need a premium membership, however I am pretty satisfied with mine already. would change it if it was a screen name created like five years ago. Thankfully, I created my dA account when I was known in the Internet as MisaTange.
