Neat feature but what if someone changed his username in the wrong way *example added a wrong latter or number* and wanted to edit it does he have to dm an admin or just wait 60 days?

You have to re-type in your password before you can submit the Username change. IMO if you're careless enough not to double-check what you've written then that's a YOU problem.

In rare circumstances if the mistake is obvious then yes, an admin may change it for you but I wouldn't bank on it.

No but like what if someone changes their username and youre trying to find soemthing and you cant because you didnt know they changed it
