Dumb Little Man points to a source of free foreign language courses online:
FSI Language Courses [is] the home for language courses developed by the Foreign Service Institute. These courses were developed by the United States government and are in the public domain. This site is dedicated to making these language courses freely available in an electronic format. It is an independent effort to foster the learning of worldwide languages.
The site contains a discussion forum and access to study materials for many languages, including:
In addition to its own library of information, FSI Language Courses links to other useful tools such as various “learn a foreign language podcasts” and this website about teaching yourself languages.
I know a smattering of German and Spanish (and recently I tried to teach myself Latin). I regret that I’ve never had the time or the inclination to learn more — foreign languages can be immensely rewarding.
