I am currently working on a project that involves the development of a log book/diary. This project is tailored to a specific field of interest (or topic). It contains a fill-in-the-blank format for which I will be providing the user with "prompts" to record their thoughts. My preliminary searches have not found anything like it on the market. In order to prevent others from capitalizing on this idea, I'd like to protect it. Is registering this idea with a copyright the way to go? More importantly, is something like this able to be copyrighted?
