A big image for a big site. I found this just a few months ago and have been hooked on it ever since. Tons of virtual seasons for tons of your favorite shows are there for your perusal. After a few problems with their initial attempt, they're now showing their own Season 6 of 'Sliders.' And of course you'll want to check it out, because every PVT series is always high in quality.
I also owe Phoneix Virtual Television a debt of gratitude for getting me started on my own Season 6. Without that site, I never would've found great script-based fan season sites like 'Millenium' and even 'SeaQuest 2047.' It's those sites that impressed me enough to convince to try a season of my own. Of course, by that point, Phoenix was already starting to prepare its own season of 'Sliders', but that doesn't make me love the site any less. Give 'em a whirl.
Fantastic 'Sliders' humor for those who'll get it. Man, this stuff kills me. My personal favorite is "Colin Mallory's Can O' Whup Ass" — now that is absolutely classic.
Say you just stumbled across this site, haven't watched 'Sliders' in four years, and can't figure out who this Diana person is, let alone why we keep referring to Quinn by his last name. Well, become a 'Sliders' genius in about 15 minutes via TemporalFlux's Dimension of Continuity. All the inside dope to make you look less like one.
On the other hand, if it's knowledge of the specific episodes that you're craving, well, there's a number of places you can go for the ins and outs of every installment. 'Earth Prime' is one of them, and one of the best.
