This whole thread seems wrong to me for those who wanted it to keep the changes unnoticed.
Start a new account then. I don't get the point of keeping the same account and not wanting anyone to notice the change, especially considering the squatting risk.
Agreed. I don't think you can get a name change if theymos doesn't recognize your username, and if theymos recognizes it, many others will recognize it too. So there's no scenario in which you can change your name unnoticed.
