I am a Czech software developer who has previous experience with localization of applications. I know some other people who have localization experience.
I would like to localize the Muse apps into Czech and German. I believe that product like Muse should communicate with the user in their native language. If the app runs in English and the user is not a native English speaker, the associated mental effort will probably hamper their attempts to calm down entirely.
I would do the Czech localization myself and the German localization with help of my German-Czech acquaintance, who is a professional interpreter/translator. We are both interested in Muse.
FYI, Czech is spoken by 10,5 million people and German by over 90 million people in Europe.
Is such a proposal interesting for you?
