Translators registration
One great feature would be a translators registration form.
What I mean by that is, first, if users don't register as translators, they are not proposed translations.
If they do, they are proposed only the languages they have selected.
Plus, I have one concern, coming from the professionnel world of translation. I would like Admin to be able to restrict the number of target languages a translator can register for.
If you train you can read many languages, but you will be able to write WELL in only one or two.
Plus, it would be great to be able to register people as reviewers in their own language, if they don't mention capacities in foreign languages.
