Navigation links between chapters

One reader has pointed out to me that there are no links to the previous chapter, or the next story at the base of my current posting. Also, my previous posting links to my next story rather than the next chapter of the current story. I always assumed that these links were put on automatically by the system, but apparently not so. Is this something that I, as an author, need to concern myself with?

Regards to all and thanks for a wonderful site.
