Yes, I'm aware that you can do it that way, or you can simply sort by author in ascending or descending order, but what you get is still a list of stories rather than a list of authors, which is somewhat cumbersome. I was looking for something a little more succinct.

Most story sites do provide such a list. This site provides a wide array of search capabilities, much more than average. Jinn has done a remarkable job of organizing the site and making it easy to navigate. Nonetheless, it seemed like this might be a useful addition. I do like to look over the author lists on other sites and see who's posting stories.
