Do you want to see Arduino’s IDE translated to your own language? Do you have one hour to put into that? You can now help out by following the instructions to be found at this page in the playground. Any submissions before April 7th will be included in the next release of the software: Arduino 1.01.

So far we have: English, Japanese, and German seems to be on the way. Come and give us a hand any language … literally, any language is welcome: http://arduino.cc/playground/Main/LanguagesIDE
