Not sure if it's been reported yet, but TWCS Library has changed to STARS Library. I went to update some in progress stories today and noticed neither link will work in Fanficfare anymore.
http://www.twcslibrary.net brings up a "Not Found" error when you pull up the website in a browser now (when it was redirecting for a while). Similar with the stories in Calibre.
http://www.starslibrary.net/ works fine in a browser, but Fanficfare doesn't recognize it yet for downloading stories.
