I raised this point in another thread: http://storiesonline.net/d/s4/t1356/a-lost-story-of-magic, but thought it important enough to raise here.
A list of authors with abandoned or removed stories might be useful for readers. While they can currently see how many yellow-flagged stories any author has, they can't currently see how many were removed, or whether a given author has abandoned the site permanently or not.
This would help in identifying stories which are no longer available, help readers relocate them, and identify authors who habitually pull stories.
Sometimes authors pull stories which don't work, or which they want to rework, so one or two missing stories wouldn't be a big deal, but if a large percentage of the authors' works are incomplete or missing over time, readers would know to avoid them. (Though, if an author quits in disgust, that's useful to readers as well.)
Unfortunately, I have no clue how to implement such an idea. It's just a suggestion for a useful feature to see whether it has any legs or not.
