I tweaked the links in the sidebar widget and on the page, MMADfan Fanfic in eBook Format, so you can directly download to your Kindle using your Kindle’s browser. (I tested it using my Kindle Keyboard/K3.)
If you download to your Kindle the document with the links to the fics on it, you can use those links to download directly to your Kindle, as well. (That document also contains links to the longer fics, and those rated higher than “T”.)
