I apologize if this has been asked and answered before but I can't seem to find it. I found some books on Fictionwise I would like to get but am confused on which formats I can use. I chose the Kindle compatible where it said to but when you are looking at a book, that is not one of the choices. One I wanted says 'secured ereader' so I figure that is out. What are the ones that I can choose that would be compatible. I would appreciate your help on this.
