Jim - Loving this plug-in! I'm an avid consumer (and sometimes author) of fanfiction and have happily used your web-based version in the past. Having it built in to Calibre is just... heavenly! If you're open to suggestion on other sites to support, I'd like to request www.dramione.org
be added if/when you can. It's a small archive, but rapidly growing in both readers and stories. I'm a staff member there, and would love to be able to use this tool to help with editing and validation.
