Hello all! I recently discovered that I had made an account back when I was in middle school and would like to log onto that account and perhaps transfer that username to my main, active account. I was wondering if there is a way to recover an account without access to the email that I signed up with, as that email was (I assume) a school-provided one that was deleted a long time ago. Any help is appreciated, thanks!
