We do, however, want to help users understand that GitLab is translated and is available in their language. ## Proposal * If we see that a user has their locale language (not location) set to a language other than English, display a prompt to help them change their language * Ideally, this preference is stored on the server, so if they log in on another machine then their language preference is remembered * We should only add this prompt once more of GitLab's interface is externalised in order to set good expectations of the experience
