As far as I know, there is none. Their beliefs keep changing, and once a web site succeeds in listing them all, they add or change something, rendering it out of date.
I know there is no complete list of teachings among witless sources. If there were, it would take someone with half a brain to put them together in a semi-integrated fashion, find that some clash with each other, and just plain walk out. And, if there was a complete guide, people would have something to work with. Hounders would be able to accurately discern who is following the rules and who is not. It would be impossible to enact a hidden ban on entertainment, coffee, sports, and the like if people could see the whole list of rules. So, I am not expecting any complete list of witless rules to ever show up (and even if the apostates did manage to find them, they would already be out of date).
