LiveMocha.com: Free Online Language Learning Community

Since Rosetta Stone is no longer offering its service to libraries, we thought we'd share another neat language learning site that we found: Livemocha.com offers lessons plans English, Spanish, French, Hindi, German, and Mandarin Chinese. It's also a sort of social networking site-- users can practice conversations with native speakers of the language they're learning, or submit writing or audio samples for native speakers to analyze. Livemocha keeps users motivated with competitions and a language buddy system.
