The Thundering Looney Bin, home of the Buffy Bumper Stickers.
The Vampire Slayground: A Spike and Dru Fan Site
Domain of the Slain Remember those all-encompassing sites I mentioned on the main page? This is, IMHO, the best. Includes episode synopses and reviews, info on the music, and a section of missing scenes from the episodes. I'd love to meet this guy's friends!
The Order of Hannigan A (you guessed it) Alyson Hannigan web-fanclub.
Worstwitch's Fandom Homepage Not just Buffy stuff, and home of the fic "Passage," one of the best pieces I've read. Worstwitch has a thang for Giles, and maintains a few pages on him.
The Watcher and the Slayer I've said that the best, and most unexplored aspect of Buffy: The Series is the relationship between Buffy and Giles? Here's a site that explores that dynamic a bit further.
The Slayer's Fanfic Archive The premier collection of Buffy fic on the 'net.
Nosferatu A Buffy fanclub-slash-show archive.
The Slayerette FanFic Archive (Self-explanatory!)
