Randomly found this browsing some of the forums for games I play. This is a good example of how a company that issues a ruling should communicate to its community. The ruling in question is not subjective, so it may not apply to some of FFG's rulings, but I thought it might be a good example of what another company does to communicate to their player base.

You can even find a better example than this: MtG main site (since MtG is also a card game and pretty much a predecessor of AGoT). Explanation of rulings during disqualification:

They also have ridiculous amount of articles written by pretty much everyone important in game development and design (about 7-10 articles per week), e.g. there is series of articles (which have about 100-300 articles) that explain why MtG designs certain cards, what they are trying to improve and avoid and how they are trying to keep them balanced, etc.:

and my favorite: explanations of how they invented a mechanic and how it was updated, improved over the design cycle

Oh yes, Making Magic is by far my favorite column over at The Mothership these days (ever since Ben Blenwiess or however you spell it left Building on a Budget). I'd kill to have that level of insight over here.
