Hi, and welcome to AFF!
At this point in time, we don't have a notification system in place. Many of our authors offer their readers updates via email, Twitter or blogsites/social networking sites such as LiveJournal or Facebook. You can check the author's profile or individual stories to see if this is available.
We're rolling out new code for the archive in stages, and right now, I can't tell you if that's a feature we will have in the new code. I can tell you that if it is, we'll let you know as soon as we know, in our News!
