kindle book sharing

[jklikesrowing]

does anyone know how i can share books with friends and how do i get books from the american site?

I think the share option is still only available to US registered Kindles plus the user has an Amazon Prime account. See PCMag article

To my knowledge you can not get books from the US website. You may find that you can get books in .MOBI format from various other websites.
