On March 30, Flash Fiction Center was deleted from Kitely. However, this sim will be online again - on a different grid - for a presentation during SLMOOC17 in June 2017. Meanwhile, of course, you can always watch the video tour.
Also, if you're a teacher/trainer/librarian, remember that Flash Fiction Center - an OpenSim Archive (aka OAR file) - was created as a tool for educators to use in their creative learning projects. You'll be able to learn more about using OAR files in educational projects during SLMOOC17. Stay tuned for further details.
