I do have a question about your site, if you don't mind.
You have set up your site in a pages-based format. Your contact page (called "sign up") says, "Complete the form below to receive E-mail notifications of revisions and new Chapters."
You are using that to send info to folks who send you a comment?
That is different from a reader who decides to follow your blog, so you are going to use that to communicate directly with people who "sign-up" or contact you?
It is just my opinion here, but you should say something that you will be personally emailing anyone who signs up. Blogs, facebook, other social media etc. have the option to "follow" or "subscribe," but you don't have posts so no one can choose that option in your case. That is fine, but [opinion] making it clear that it's more personal/direct communication should be clear. Again, it's only my opinion. For your situation, it might be a good point.
something like this:
Complete the form below to receive E-mail notifications directly from me of revisions and new Chapters.
