@YTCreators Dear YouTube
Team My channel old name was Expertguru & custom url (http://www.youtube.com/expertguru ), but I have changed my channel name Expert Guru to Techmewadi. So pleased I have requested to change my custom url http://www.youtube.com/expertguru to http://www.youtube.com/techmewadi
Thanks for reaching out. Check out the 'Remove custom URL & claim a new one' section of our Help Center article on custom URLs. This may help answer your question: https://goo.gl/UTqwaV . Hope this helps.
