After one and a half years of having a YouTube account, I finally know how to change my URL.
It is very simple to change. Here are the steps:
1. Sign in to your YouTube using your Google account.
2. Click the arrow button next to your Google profile.
3. Go to YouTube Settings.
6. Key in your desired name/URL
That’s it. So if you are not following me, my URL is www.youtube.com/ETSpeaksFromHome
