Thanks to Laura for sharing this important information. I have just started on Goodreads as an author, have my first book listed on my account, and have yet to start working on giveaways (though I planned to). I am an American writer, and write in a genre that is more popular in the US (SF/F) but many of my blog followers are international peers, and I love that. I have already run into trouble trying to get copies of my book to them through Amazon (I’ve ended up having to manually send MOBI files). I recently did a giveaway on Amazon, which was only available for US residents. I was hoping to do more with Goodreads. If anyone is concerned about this issue, please read the original post in full.
