As a blogger, I fear being copied or having my posts used without my permission. I fear this happening, even more, with my book. I am so paranoid, I won't give any information out about it, except on paper or verbally...this can make it difficult to get feedback from members of my target audience. My book club has suggested buying domain names, under the book's name (although it may be changed by a publisher), the series' name, and my pen name. I thought that'd be a great way to get out in front of interested fans. The next, and much more expensive step, would be getting trademarked. Until you know what name your books will get published under, you'll just have to wait on this one!
