Some translators did a lot of crap work, translators using Automated services like Google translators can't be called even losers. SMF makes a lot of changes on the language files in every release, where this changes can be viewed, are they commented in the language files ? Or do you plan build-in translation module like MyBB ?
Regarding translators - Can you Translate Add forum as Add Category, Add Section, Add board and all this 3 for a simple task to make Category, main board and sub board ?
Or to translate profile as Edit Profile, or to translate POST as POST, or ACCOUNT AS ACCOUNT or to left 90% of the prepared package in English ?
