How to localize/translate the text?

Hello guys,
I know English is the native language to most of players
and it is also recommended speaking English on forum
I'm here just to ask whether it's possible to access/modify the language displayed?
I heard there is a RU language version client, may I have its author's name or the way change client language?
If true, I can work for the Chinese simplified /Chinese Traditional translation.
