Welcome to the community. Translations for the game are worked on by the community here: https://translate.revolutionarygamesstudio.com/
There’s also a thread to discuss the translations: Thrive Translation and Correction Office [TTCO]
I wasn’t really sure how to categorize your post as it kind of doesn’t fit any category that well, in the end I decided to put it in #not-thrive as this just seems to talk about some random stuff about having a specific language community for the game.
