From Raimond Eisele:
FanFictionDownloader is a simple application to download FanFiction. FanFictionDownloader supports several different FanFiction archive pages to download from. Click on "Supported Archives" in the left menu to get the list and learn how to use them. Your downloaded fanfictions can be saved in 14 different output formats. You can choose between the following formats: EPUB used by a lot of e-book readers, PDF, MOBI, RTF, TXT, HTML, FB2, LIT, LRF, OEB, PDB, PML, RB, and TCR.
What's new in this version:
Version 0.7.3 has fixed FanFiction.net or Fictionpress Problems.
Everything else is con. I get a pdf that has titles, and chapter heading, but no body. The story is not there, just the titles and chapters. I have reinstalled several times. This program is unstable and not worth the hassle.
