Well, I did vote, but, to be honest, I checked the 'other' option in all three questions too - but not just that one!
There are just too many fanfics I've loved - "Faux Pas" and "Kidnapped!", which you include, LabRat's "Masques", Becky Bain's "Ad Astra Per Aspera", Gerry Ancklewicz's "Blind Spots" and Irene Dutch's "In Cat's Corner" are some of the long ones. And I also find myself totally in love with some short fics - some are comedies, like Anna Belcher's "Lois and Clark: The episodic adventures of Superman", "Smurfed!" by Alicia U. and Rivka, Messenger's "Mixed Messages" and others. Other are WAFFy - Supermom's "I've Got This Friend" and Kathy Brown's "Into Each Life..." come to mind. The good thing about our fandom is that most, if not all, fics are at least decent.
My favourite WIPs are the three I've been reading: "Damaged", "Wedding Consequences" (although I'm a bit behind at that) and Mary Potts's "One Strange Year" (not listed).
My favourite author now... Well, to be honest, I mostly care about stories. I gave a vote to Yvonne, because... please, don't make me explain because I'll start thinking I was wrong not to vote for the others, too. Anyway, above there's a fairly wide list of authors whose stories I've enjoyed. Add also Cyad, Paul-Gabriel Wiener and Mary Potts and I think you have my most favourites.
I really hope that my reply doesn't offend anyone. After all, I'm a writer too

But, anyway, I think it's obvious that I couldn't possibly list all my favourites.
See ya,
