That's really awesome to hear! I work on the Stanford edX team, but we don't see a lot of feedback from our off-campus users (even though there are lots of them). It's great to know that MOOCs are actually helping people out. In case anyone hasn't heard of our site (it's a little smaller than the more well known ones), we run a public edX instance at lagunita.stanford.edu and maintain forks of the edX repositories at github.com/StanfordOnline.
Kiloreux and others who have benefited in similar ways, PLEASE email your stories to Coursera, edX, MIT OCW, or any other sites whose MOOCs have helped you. Sometimes, they are sitting in a meeting room discussing whether to discontinue some free aspect of the service, and your story will be enough to convince them to keep it going a little longer.
You might feel insignificant off in some far corner of the world, but when the creators hear your voice, they REALLY care what you think.
