How do you change your channel name on YouTube?
When you go to your channel page, there will be a button towards the top of the page that says "channel settings". From there you go the the "info and settings" tab, and can name your channel. You can't change your username though (which is a total pain).
Use the name change button. You'll find it under the italian section labelled 'fruitlupio'
To change your channel names on YouTube, sign into your specific account and access the settings page. Type the new channel name on the box next to the 'Title' page and save its settings. Check out http://www.ehow.com/how_8208216_change-channel-names-youtube.html for more of these details.
