We're in the process of revising the archive's code, and at the moment, what we recommend readers do is add the story to their author profile, as "Currently Reading" or "Recommended Reading." They can then store a link to that story for easy access. As the new code is written, tested and rolled out, new features may be incorporated, so as an author myself, we can all hope.
One thing some of our authors do to open dialogue with readers is to offer Twitter/email updates or even maintain a Facebook or other social media site to let readers chat about the story. These are ways to connect with readers directly, and get some valuable feedback. Many people are shy about reviewing, because they feel they won't say anything relevant or interesting, and others don't like the recaptcha feature that keeps the archive free of spambots. But by finding a creative way to reach out to readers, you can often open a lively dialogue.
