User blog comment:Kevin08015/When Subscribers Requirement will go up and how much you will need!/@comment-27157616-20150108164246/@comment-25386934-20150109044051

The ruling is already in effect. It has been for a few months now. This only applies to channel that were created after YouTube made the new custom url rule. I am aware of the first fact because my Youtube channel, made a number of years ago, has kept it's custom url (becasuse pre-2013, your "custom" url was just your account name), though I have since changed it to my full name.

I cannot tell you if you will be able to change your URL from the custom one you currently have. Since my account is for personal use only, I do not have subscribers, so I can't test this for you. My best geuss is that you will have to keep NLXArcadianGamer, as when "Custom Url" was introduced those with Youtube accounts before they update could not gain one.

Don't worry though -- in the new system YouTube sends you automated url choices, from which you have to pick based on your name, so Nicklordzero might not even be offered to you. If you grow a bit more, you can contact YouTube about having /Nicklordzero as a redirect.
