I play FNMs at a relatively small store. There isn't a judge that runs the FNMs or any that consistently play there (the crowd is casual for the most part). I know the rules fairly well and the people that play at the store trust me enough to ask rules questions. I want to take the rules advisor test so that there's at least a semi-official source for answers to rules questions at these FNMs.
What steps are there to taking the test and becoming a rules advisor (ie: do you need to talk to a judge as if you were trying to become a L1)? What types of rulings are rules advisors allowed to make?
