We've also begun accepting definitions that other users have added for these other languages. So as more users start to use these features and add translations while practicing, we'll gradually build multilingual Chinese and Japanese dictionaries aimed at learners--great! To add a definition in another language, just edit it and use the "submit as correction" checkbox.
I've started off allowing you to choose from ten source languages to start off, just based on popularity, but we could easily add more. Some of these languages don't have many definitions in the system yet, but as we amass more vocabulary sources, they'll start to rock. I'm looking forward to Chinese-Chinese study myself. If your language isn't in the system, and you want to start adding a bunch of translations for it, let me know and I'll add it.
We haven't started translating the rest of the site interface into these languages; that'll be a while later.
