FOREX: What/ where is the best FREE source of education on the web for a person who wants to learn how to?

… trade on the Foex? I am a beginner, and I specifically want to learn about the basics, how to spot trends, tradeing techniques, etc..
Even if you want to recomend a book- that would be helpful. (FYI: I cannot afford a pricey course, so any recomendations to that fact will not be considered).

THANKS!
