How to override "Email has already been accepted"?

Question

I would like to replace this error message with something more instructive to help the user understand what to do next. Unfortunately, I can not find it anywhere in my source; where does it come from and how can I change it?

Find config/locales/YOUR_LOCALE.yml and set the following key:

 errors: messages: taken: "has already been taken"
