Earlier this year (around February) they stopped allowing name changes because it started hurting the server and making PC move really slow. So, we don't have name changes anymore. Instead, if you want a new username you'd have to create a new account, however you cannot act like you're a new user.
Your avatar, that's how I remember you. We definitely haven't spoken in a really looooong time. A lot has happened, but things are doing great, thanks. :)
