I’m very interested in languages (I have especially gotten into constructed languages during the past few years), and would really like to learn more. And it would be really convenient to be able to learn from a free online course-- however, most I have seen are very lacking. Can anyone recommend a good free online learning guide to any language (not a ‘class’ per se but preferably a series of web pages telling you what to learn. A good example is this. I don’t care how difficult the language is, as long as the course itself is rather user-friendly and doesn’t assume too much about what you know. Thanks a lot.
