So far, I've managed to use the Wayback Machine and other tools to acquire complete lists of nominees and winners of the 2004 and 2005 Blue Sun Fandom Awards, the 2005 and 2006 "Best of Rayne" awards, as well as a relatively up-to-date (but by no means complete) list of the nominees for the never-awarded (am I correct in that?) 2007 "Best of Rayne" categories.
What I'm having difficulty with now is the "Pretty Deadly Awards" for 2008-10 (nominees as well as winners), as well as the list of nominees from the 2011 Awards, which were going to be re-held due to software failures in the system but never were.
I've been able to identify one winner of a 2008 "Pretty Deadly" award (sunshineali's "We're Off to See the Dentist"), and a bunch of winners but only a very few nominees from the 2010 awards (wins by goddessofbirth mostly, plus another win for green_amberjade). I remember that The Frisky Firelily had fics nominated in many categories in 2011, but the only specific nominations I have a record of for that year are my own few.
If you're interested and able to help with memories or off-site records of "Pretty Deadly Awards" nominees and winners in years past, please let me know! And, of course, I'm happy to share whatever information I've been able to gather with anyone else who's interested or looking to get back into reading Rayne fic again.
Thanks in advance for any help you all can render.
