See the Liviing Aboard column in December issue Houseboat magazine. I don't think it's available online. Good update. Too many people now giving courses on what used to be (and is no more) in fast-paced Internet
commerce. Save your money
and learn by doing or be sure the course is about monetizing, not just knowing html and SEO. Lots of people know computers
but fewer know how to fully harness the Internet
to make a living.
