I can't say enough about this site. From TemporalFlux, its main purpose is to answer new and old questions about SLIDERS by looking at rare script outtakes, memorabilia, and whatever Tf can find!
From Chaser9, this site explores what might have been had the original cast returned for Season Five. Trust me, it's not what you're expecting at all. Great fanfic, and it's also the mother of The Otherworlds.
From Slider142, this site has a lot of great extras, including short stories, an original novel called "Fable," a page devoted to Sliders, and one to saving the show! Worth checking out!
From Blinker, this truly insane site is one of two to house the archive of "Parallel Dementia," an interactive fanfic game created by Thomas Malthus. Also contains Blinker's Top Ten lists, Sliders from Earth 69 (and you thought our world's show was bad at times), and Colin Mallory's Can O' Whup-Ass!
From SliderSarah, a great page with information, episode synopses, pics-a-plenty, fanfic, and the "Bring Back Sliders to the UK Campaign". Also houses the Parallel Dementia Archive! Definitely worth a look-see!
From "SlidersCentral" of the Dominion Sliders board, this site houses many theories, fanfics, and other interesting items!
Steve (Vortex62) uses Java applets to achieve an impressive look on his site! If you're looking for a great all-around SF
page with good info on Sliders, check this one out.
From Slider43, a familiar looking site with pictures, news, and an episode guide.
Sliders: The Timer
This very cool site by Gregslider of France contains many items of interest, including his personal interview with Robert K. Weiss as published in Generation Series, a French Sci-Fi magazine. Special thanks to Greg for letting me use the pic of RK!
