I've completed Simplified Chinese translation. This is my pull request.
current i18n policy (2 letter ISO code) can't distinguish zh-cn, zh-hk so on.
also the time format,
maybe an issue.
translations: Chinese(zh) translations by Shuyu Wang aka andelf
Wow, very nice!
I'll check it out.
mod_translation: Add zh to languages list, add Shuyu Wang to translators
Will check if we can add support for language variations like zh-hk
Created #499 for design discussion of this
