Sign up your Amazon books to allow your readers to request a Kindlegraph from you. A Kindlegraph is a way for an author to autograph a book electronically. I have been doing this for my readers since I started publishing in 2011, but was reminded of it this weekend when I received new requests.
You will need your Amazon ASIN number to sign up and I believe each book must be listed to be eligible. The directions on the site give you all the information you need. Happy Kindlegraphing! (I believe I owe my knowledge of this to either Kim Jacobs or JM Madden who told me about it last year.)
