I usually click on the authors name and then from there click on his stories.
Good idea, but unfortunately, visitors to the site can not access profile pages unless they are registered members. That's one of the reasons I encourage people that visit KB to register for an account.
An author would need to put an index of stories with links on his profile page. It's not that hard. I would encourage authors to do that for the reason you stated WIW4. Another reason to do so is to make it easier to find other stories by an author, should you really enjoy one of his or her stories.
Please know that any author needing help in setting up an index of stories on their profile site, just need only ask me for assistance. I will set up your first couple of stories. From then on, you could just look at how I did it and continue to build your library.
