Creating membership site or pages

i noticed that much of my questions are not answered and much of the times i got no comprehensible answers i think this is not friendly to people wich or paying you money for support. I hope this question will be answered. If i can not make a membership area using your system can i make 4 menu pages then maybe for example free bronz silver and gold and protect these meny pages. Is this possible or do i need to make categories. Could you please aswer?
