Hi there, sorry for the late reply. Based on your profile, I assume you're better at english.
Currently, the english translation job is half-done for case 3, so for now we don't really need translators.
What made you find this project? And what is motivating you to help out on the translation?
If you want to discuss this further, it'd be best on discord, but we can do that here if you'd rather not for now. No need to voice-chat either way.
