Look at the
Staff List. Each area of the site has an administrator who is in charge of that areas of the site. Susan normally defers to the other administrators so she is pretty much in the background most of the time. Anyway, PM either the administrator in charge of the area or if you are friendly with somebody who works in that area, you could PM them as well. For example, I am a senior forums moderator and if you are brave enough to take that on, I would be willing to share with you but in the end, Cindy would make the final decision.
ThaliaNyx is the minecraft administrator and staff members in that area are responsible for world creation and enforcing the rules. The TOS still apply as well as any minecraft specific rules so you would be the police as well as a builder. I have had some dealings with SilverWing on the forum and I believe that she would be more than willing to answer your questions.
