The StoryViewer / GamePlayer has been rewritten. unfortunately, there's not much of a visible change (however, comments are now tied to username), But this is necessary to bring even more advanced features into the stories created here.
None really -- it uses the same architecture and logic, but I had to rewrite ("translate") each line of code, one by one, from the old language to the new (.NET) -- over 1,000 lines of code in total.
