Is it possible to change a nickname here?

Maybe moderators can change my username to EmilyGraceSeville7cf? If it’s not possible, can be my account deleted by admins (to let me create a new one with a new nickname, I don’t wanna two my accounts exist at once)?

Changed as requested.

Let me know if there are any issues with it. I don’t know if this will impact your login, but if you have troubles, contact us via IRC, or Telegram.
