SRL Archive - RuneScape News and General

I want to start my own YT channel for runescape guides and even go live-streaming on Summer. My point is that I need to change YT channel name, I cannot do this cause I only get my Google+ name and surname as YT channel name. Can anyone help me with this please.

Try clicking your name on the top-right hand corner, go down to 'settings', then next to the 'Name' section right under where it says overview, I think it will say something about changing your name.
