I've seen the FAQ button on threads, so I assumed that there was a FAQ about pathfinder specific questions like "how does stealth work in this situation?".
However, the links at the top of the page seem to only point to a general FAQ about things like "what is pathfinder" and "how do I use the messages boards".
Is there a link somewhere that I'm missing?
The best way to get to the FAQs are to click on the Pathfinder Roleplaying Game symbol on the top of the left hand column. Look for the book that you would like an FAQ for and click on it as though you were about to order it online. At the bottom with the reviews and product discussion there should be a tab that is labeled "Frequently Asked Questions". It can be a hassle to track down if you don't know exactly where they are. If you are still having trouble I'll gladly link you to the other FAQs as well.
Be warned, the FAQs are purposefully tricky to find since they're currently incomplete/underdeveloped and updates are, at best, infrequent/irregular. For most issues you're better off searching the forums for similar issues and seeing what the general consensus is (which, oftentimes, there isn't). On occasion, if you're lucky, the developers have chimed in on threads to contribute semi-official answers to questions.
