Joe Vitale's is also excellent - albeit not free.
(Yup, that's my affiliate link - for a promotion that Joe is running
right now)
But a free way to learn how to write like Joe Vitale, is to actually read what he's writing.
Read it, disect it, analyse it.
Try to figure out what it is about Joe's writing that so good.
Try to imagine what must have gone through Joe's head as he was writing.
Ask yourself what kind of mindset one would have to posses to write that way.
Imagine how Joe is thinking about his readers - what are the values that drives this belief?
Then duplicate the writing style or how his pages are laid out. (duplicate as in heavily inspired, but definitely not copied verbatim)
Also, read Lynn's newsletters and her blog posts - they are captive as well
