iAuthor - Internet Advertising

Through Twitter I found iAuthor, a website that lets you essentially advertise your books for free. It's pretty easy to do, just upload the cover image, add a blurb and pertinent information, links to where the books can be found and you're on your way. You can also list the books in what they refer to as Themes, categories that help channel your books to potential readers. I've been using it for only a couple of days now but the first two books have been getting some notices already. They're on FB here - https://www.facebook.com/iauthor, on Twitter - @iAuthor, and the website is - www.iauthor.uk.com
