Language Skills

A friend lamented yesterday that he didn't know a language other than his native tongue and that he had never really left his home country. Up until a few years ago, I was in the same boat. While I can't do much for sending someone to foreign locales, here are a few options for acquiring new language skills:

• Foreign Language Lesson Podcast Collection at Open Culture
• BBC Languages
• BBC's Muzzy language courses for kids
  
• Foreign Languages and Literatures through MIT's OpenCourseWare
• Rosetta Stone language software
• Living Language audio and text collections

If anyone else has suggestions, I'd love to know them.
