At this moment, there are no fees. And amount of fees is something determined by GA. So, join GA, and make sure GA isn't going to enact fees - problem solved. And, it's not like people would vote to create fees upon themselves, anyway - they would rather donate voluntarily, instead.
Is it defined what to do in case of conflict between rulings of GA and rulings of Council?..
What's needed is a clarification which rulings can be made by Council and which by General Assembly.
