The nfics have their own awards, called the nKerths. It's not run quite as often, due to the small number of nFic stories. It last took place in 2005, from what I see, so it's probably due. The website is

The Kerth awards are only for the lower-rated (PG-13 and below) stories, so that everyone who votes can vote for all stories, no matter what the age.
