Two days I ago we received email from Hiroki Yoshino, a guy from the japanese web design company OFFIBBA (check it out - amazing work!). He sent us a japanese translation for the web interface for the upcoming LimeSurvey version 1.50 - which is now already checked into the development version. But not only that - he also announced he will translate the online documentation in our Wiki - and just today he did most if it! All Japanese LimeSurvey users will love to see this new documentation translation. For us it is exiciting since it shows that the LimeSurvey community is growing steadily - and we really love the japanese chars!
If you (yes you!) want to add your language to LimeSurvey or updating existing ones you can start here or here - if you have any questions regarding translations just leave me a message.
