The only prob with that is... most Site Admins weren't too busy with their life or their site to be on PC. And I say prob because they had their own forums before and they ran things like they wanted over there. And then they came to PC, they knew nothing about how PC worked form the Staff point of view, and they would do things on their own. It should have been "Hi guys, I'm the new Site Admin here. I'm the newbie here, and you guys have done a great job running the forum. If you don't mind could you show me how it's done around here so I don't do something I shouldn't?" and then no probs would have come up. But we had Admins making forums, we had Admins Modding people, and so on. They would go "I'm an Admin, I'm above you, I can do whatever I want!", even if that Staff member was on the Staff long before that Admin came along.
Don't get me wrong, we've had some really good Site Admins. But that system doesn't work because you had someone going from member to Admin thinking they could do whatever they wanted on PC.
