If you see a kingdom, in principle and in practice the emperor has no clothes. No single person has any special power or ownership over articles. If someone acts that way, you get to tell them what you think of it, if you like, and you'll very much be in the right. And if you are, others should agree and side with you.
There aren't moderators as such, people are supposed to talk to each other, directly. If you don't like how someone seems to act like they own the place, it won't change unless you tell em how you feel!
The thing is people who aren't afraid to give their opinions tend to talk over quieter people. I'm afraid I don't have a very good cure to offer, but please don't feel like anyone's too big of a power-user to have a little respectful, civil chat with. Please, template the regulars! They either respond politely, or they lash out and make an ass of themselves in public.
The problem is the rules apply equally to everyone, but the power users know exactly where the line is and how the bureaucracy works. "The law, in its majestic equality, allows administrators and newcomers alike to revert edits per policy, report 3RR violations, and open AN/I threads about people they don't like"
