Default language for role I'm building a website in French as default and only front language but I have to figure out how to do this:

I have administrator and manager roles, both are ok using the french language for both front UI and Admin panels but I also have a role "normal-users" for wich I want to set the default front UI and Admin panels to english by default at registration. How can I do this ?
Take a look in this topic below

How to set the language for the user while it is created?

Just read it quickly, this seems  to be what you need?
