Mainly for the hardcore, and perhaps of historical significance, the old Kenneth Folk Dharma forums, which were active for perhaps 4 years (and were then mysteriously deleted one day by an apparently overzealous third party free domain owner), have been restored on the Awake Network site as the Kenneth Folk Dharma Archive.
The bulk of it is in the "Original" section, which contains a vast number of practice journals that are of potentially incalculable value, although similar material can be found on Dharma Overground or Awake Network. The V2 section archives the short lived and ultimately failed attempt to revive the forums after their sudden disappearance.
Then there's the plain old Kenneth Folk site in it's current incarnation that contains a lot of the instruction topics from the original site, but frustratingly doesn't seem to have quite all of them. There is still an archive that points to those, here I'm talking about the topics that show up in a box on the left ("Start Here", etc.).
