I'm sorry if this has already been discussed and/or posted somewhere; I'm not very familiar with the site yet, YET I already realize my username should match my tournament entrant/Twitch screenname (and not my YouTube sn - don't ask me why it's different, I wouldn't be able to tell you what I was thinking).

Can I change my name - or have my name changed - from the current ("Zenothys") to my actual ("Sync") screenname?

@Zenothys, @itsagifnotagif (I think you're a bot), you can change your username in your settings under "Account" on "Change username". Or here's the link https://www.speedrun.com/settings/account

But the @Sync username has already been taken. You used to be able to request old usernames, but I don't think you can anymore. As the support ticket type now says "We do not manually handle this type of request. If you cannot change your username then that name is not available."

The @Sync account doesn't have any runs on it, but it was last online 1 month ago, so I think it's active enough to not have their username taken.

You could message site staff about getting their username, but you might not be accepted.
