You can try editing your account (I don't discuss that here) but it was your choice when you created your channel to type that in. You might have to create a new channel with only the details you want to share.
Always that someone click in my Youtube Channel, he see my full personal name (youtube/user/MyFullPersonalName/etc/etc) but, actually, I want that he see my personalized channel name (youtube/c/PersonalizedChannelName/etc/etc). Is possible change it, How?
If not, is possible to occult my user URL name of some another way??
Thanks a lot!
