ebook sharing

Hi I have a new ebook and I would like to share it with as many people as possible. I might share it on kindle as well, but as I know they have a minimum price, it would be better to offer it for completely free. I was thinking of warez forums (ebook section),pastebin,some dock sharing sites or...
