It might be nice if the site allowed authors to post a synopsis for a story, showing how it was expected to pan out, with this legacy post only appearing when (a) the story got the yellow 'incomplete and inactive' flag, and (b) the author had not visited the site for some time (6 months, say)? Obviously, many authors would not want to take advantage of this, but others writing long-running serials might like to leave a note of how they expected it to end. As the story progresses the legacy post might need changing!
Edited to add: I would love to know how, for example, Raven Soule had intended to bring Tycoon to a conclusion! Also, some authors might prefer the legacy pist only to be visible to fellow authors, in the hope that one of them might care to try to continue the story (without the handicap of the plot having been revealed to the general readership).
