I made a new account, but then I learned I can rename my old account. So I renamed this account to Deletedaccount420 and now this account is taking up the username and I can't rename the other one. Is there a way to reuse my old username or change the account name change? Will the old username be "available" any time soon? Can I contact support to see if I can undo this username and keep this account instead? Thanks in advance.

Edit: This is a brand new account, made because I didn't know I could rename the other one. Haven't edited any pages yet. And the "aka (old username)" thing is also something I hadn't anticipated. At this point, the best solution would be to reverse the username change or at least have the username available to make a new account, so as to avoid featuring my old username in the profile.
