Livemocha offers basic instructional tutorials and exercises in some 30 different languages, but the service's real value is in its community. Livemocha has assembled more than 6 million members, each listing fluency and linguistic skills. When submitting an exercise, you have the option to get someone in the community to grade your effort, correcting your pitfalls and helping you hone your skills through the careful lens of a native speaker. It's a social approach to learning a language, and one that's cheaper than pricey software like Rosetta Stone — basic courses are free, and utilizing the community costs only a small monthly fee.
