But couldn't we then extract the Original strings of TH and put them in our own English.lua and translate all of that? What is exactly the problem with this, doesn't sound too difficult too me or do I forget something? We could use Crowdin (Alan works also with this and it works perfect for him, also translated some strings of the Android port) or Transifex for this, which are both free for open source projects?
And if we then change all Lua files to .txt files or something (they don't work with LUA files) we could translate everything really easy.
Edit: also OneSky looks like a promising translation platforms and is also free for public projects.
