CSV-Import has been implemented and deployed. You can import your translations easy with a few clicks.
Next step is to let you select all languages which should be used and translate to them automatically.
What about special technical terms? I work in logistics. And I often need to translate from French and English. So I need to understand clearly what my colleagues write to me. So I searched a lot and finally find a good translator - translate.com. This service can provide much better service than a lot of others. Now I am completely sure that all my correspondence will be translated correctly and without any mistakes.
