Nonnies often ask one another for research help on topics that are obscure or esoteric. That's why the “Fic Research Thread” was invented. Sometimes there are also “Ask the Experts” threads in which nonnies offer answers to questions in their particular fields of expertise.

Over the years, FFA has had far too many “Fic Research/Unfuck My Plot” threads for all of them to be listed on this page. FFArchive/Dememe has them indexed going back to the start of 2013. However, some earlier examples are provided below.

• Ask the Experts (Nov. 14, 2011)

• going crazy — “I'm trying to figure out what a bachelor pad in Victorian London would have looked like. I was using Sherlock as a reference but other than that I can't find anything. What do you think anons, what would a victorian bachelor have?” (Dec. 23, 2011)

What types of roses were the ancient Greeks familiar with? When exactly did the fact that the light we see from stars is years delayed enter into the popular consciousness?” When other nonnies asked them if they'd like to do research for them, the nonny replied, “In case anyone wants to take me up on it, I've left a comment at the friending meme.” (Jan. 20, 2012)
