I've not been here very long, so I expect my opinion on this is going to be either incomplete or misinformed in some fashion, but I'll share my thoughts anyway.
I honestly don't think the forum is staff centric; on the contrary, the staff members that I've spoken to are quite approachable, and member feedback isn't ignored; if anything, it's sought after. Of course, without knowing how staff operate behind the scenes and how decisions are made I can't say for certain just how staff centric the forum is, but...well, I don't NEED to know that, and neither does anyone else not on the staff really. It's up to the staff to make decisions regarding the forum's structure, and be responsible for their individual sections.
It's the same on every forum; it's not a process that needs transparency unless there is a serious disagreement, or unless an individual has a specific question...and then it's just a matter of clarifying decisions, which in itself isn't an unreasonable thing to ask for or a difficult thing to do. Just saying "We're not doing this because [insert reason here]" if members ask for something, or saying "We've given you a warning because [insert reason here]" if a member thinks they've been dealt with unfairly; that's all the transparency you really need.
There is a feedback and Q&A section for members to raise questions, say what they think of existing staff members, and make suggestions about how the forum can improved. Short of giving all members mod powers, I don't really see what else can be done to improve transparency. Unless you want to make the staff section of the boards (I'm going to assume this forum has one; it'd be very strange if it didn't. xD) visible for all to see anyway, but that would be quite extreme and highly unnecessary, as the main way members can have their say on the running of the forum are more than adequate. Most forums I've been on don't have a staff feedback thread, and a lot ignore their Q&A sections. Mods are unapproachable and often little better than machines, there to do their job and nothing else. I've been chatting with some of the mods here since the day I joined, and I've never really felt intimidated by them...well, not because of their position, anyway; I'm a naturally shy person until I warm up to people, but my point is that the staff I've dealt with here have been both approachable and reasonable, at least to me. Maybe I haven't been here long enough to have an argument with one yet, but until that happens, I can only base my opinion off my current experience. I could go and do something controversial to provoke one and see what happened, if it'd help? xD
There is always going to be a level of disparity between staff and member; it's what comes of having the position, and of having the power to make decisions and manage sections; of being able to do what members can't. Communication is always good, and when it comes to major decisions or actions on member feedback, it's nice to know what is going on, but beyond that? Well, members don't really need to know; it's what the staff were chosen to do, so it's up to them. That doesn't make a forum staff centric, and if the staff are actually doing it, that just means they're doing their jobs properly.
Anyone who thinks that you can only get the maximum enjoyment out of a forum by being on the staff needs to shift their thinking a little. Being a moderator is a privelege, and it does make the experience more enjoyable by and large, but you can have just as much fun on a forum being a regular member. Being a staff member can be quite stressful and take up a lot of your time, especially on larger forums: you have expectations and responsibilities to fulfil that you don't have as a member; it's not all fun and games all the time. That kind of complaint, in my opinion, typically comes from faulty perceptions, or from people not knowing exactly what the job involves. Obviously I've not been a mod here, but I HAVE modded large forums in the past, so I think I have a fair idea in a general sense. Staff members are well-known and often popular, but it is quite possible to be both of those things without being on the staff, it just requires a little more time and effort usually. But that isn't the fault of the staff or a flaw in the system; it's just something else that comes with the job. The forum isn't going to work very well if the mods are all despised, is it?
In short? I'd say just carry on as you were. So long as staff members are active, helpful and, most importantly, approachable, and member feedback continues to be taken into account, I don't see the need for greater transparency or drastic changes. If it ain't broke, don't fix it.
There is a high probability I'm ignorant of a lot of things, or misinterpreted this topic; as I said, I haven't been here that long, and I've not really noticed any issues. The most ruckus I've seen in my time here was concerning something Sodom said, and that was primarily sparked by a troll I believe. But maybe I've not noticed anything because there hasn't been anything to notice. But that's just my two cents on it~
