I basically agree with this -- the password system is already incredibly arbitrary and too easy to manipulate to be a good indicator or whether or not someone has actually read the rules/FAQ, and changing it to something equally arbitrary and easy to manipulate isn't going to make it any better. Something quizzing you on actual information in the FAQ, like how many Pokemon can you have, or asking which rule you like the best and why, would do a much better job, if you guys really want something like this in there.
