The idea is pretty simple:

use the Lang-8 system for translate each game language string, sharing the job between group members, so funny so fast ;D!

Q: Why lang-8?
A: Simply couse lang-8 have a good and integrated system that make this hard job possible: firts of all correction system, group system etc.. etc... (and not last, here we talk all about language!) ;D

Q: Who you are?
A: I'm italian boy and i like play game in my language, i like programming too of course, i like other cultures, i'm actually studying tourism sociology! ;D

Q: How this is possible in practice?
A: Ok, suppose we have a game that support few or just one language,

1 - first step is identify where language file are in the game folders;

2 - second step "decrypt or unpack" if necessary these files (not in this place);

3 - third step make it in a right form so we can post plain string text in Lang-8 system;

4 - fourth step, translate it string by string, play your game in your language!

Q: is this right place for do this?
A: absolutely Yes, just follow some rules:

1 - DONT post anything illegal!

2 - DONT speak about warez terms or something like this argument!

3 - request and replay about "program, extract and handle text" if necessary in a serious way!

4 - Keep in mind we must do just an amateur translation job!
