Neither were promotions. It was suggested by substance that I post my newsletter articles to this site and I am entirely new and not completely sure of the rules. I do book reviews for a living. Sometimes I post them on my newsletter. The newsletter is mostly for my fanfiction readers to not miss a chapter and receive it directly into their emails. I don't promote anything intentionally, but it is hard to talk about things without naturally mentioning certain things. I am still learning this site.
