Translations
Keep your profile in more than one language. A local-language version is not a translation of your English one — it is written for a different audience, and both are yours.
Primary language
The language your profile is written in today. Every field you have not translated falls back to it, so this is asked first.
Language versions
Each version is written for its own audience, not translated from the primary one.
