I just went to FFNET and downloaded @ 10 stories. FLAG seems to be as fast as fanfiction downloader. I actually liked FLAG better because I DL fic as PDF's and the PDF's from FLAG don't have all the extra lines of code that show up in pdf's from fanfiction dl'er. in between the chapters. I will be using it in the future.
Thanks for asking about it because I hadn'y heard of it before. I guess when i have something that is working I don't go hunting for something better.
