I am currently looking into Issuu which ia a magazine-alike ebook builder and host. http://issuu.com/ - there are many examples and as a member you can pick your samples for a personal book shelf. It is said to allow all sorts of formatted text, but it was not possble to upload a mac-made .key (like PPT) presentation). I'll see if I can save the stuff in a workable format and upload it to Issuu. Anyone knows this tool?
