Creating language (done only once):
- post here the language name, language_COUNTRY code, country ISO_3166 code
http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2, character set (example: Polish, pl_PL, PL, ISO-8859-2)
- download locale file (in attachment), create a directory named as language_COUNTRY and copy the translation files from already existing provided languages
- download and install PoEdit
http://www.poedit.net/download.php- click on the .po file of your newly created language directory, the PoEdit will launch
- go to catalog/settings and change the the country, language, characterset to correct one, also delete all existing translations in the wrong language (since you copied it from existing language file) then save the modified file
Editing language file (done many times):
- download and install PoEdit
http://www.poedit.net/download.php- download locale file (in attachment)
- click on the .po file of the desited language
- edit things (really trivial)
- click save button

- zip the archive (only your language to avoid confusion, delete all others!) and make an attachment or send it some other way
After creating language step is done and you provide first edited language file (it does not need to be fully translated, it works fine as half translated, just make sure some text with national characters appears so we can check if everything works properly) I will add the language to the game.
