After posting a new chapter to an existing story I got an email from a fan telling me how much she enjoyed my story and that it lead her to check out my other stories where she found one she liked even more. As an author I can see the basic statistics of my stories, their score, how many weekly and total downloads and so on.
I was actually pretty surprised to see which of my stories were the most popular. When The Dam Breaks has the highest score and most downloads by a good margin. I may have to add an additional chapter or two to it, or write some similar stories mother/son or squirting stories, or a combination of the two.
