I just built this super cool system for translating Quizlet's interface into different languages. You can already use Quizlet to type in data in other languages, but this will actually translate Quizlet's English interface (the navigation, the instructions, etc.) into other languages.
It's ready to be translated into any language (except maybe a right-to-left language like Hebrew). So if you're fluent in any language other than English, send me an email at andrew@(quizlet's domain) with what language you can translate Quizlet into and a little about yourself and your fluency level. Experience with (very) basic HTML will help you, but it's not strictly required. You will receive credit in the footer of every page on the site for people using your language. The system for translating the site is super slick - you'll enjoy it! ;)
I'm also looking for an expert systems engineer to work on making Quizlet faster. If you're interested, I've posted the details on Craigslist, and I won't repeat them here. Thanks y'all!
