From reading through all the comments in the last few threads that popped up, I've come to the conclusion that there is probably a bigger problem here than I at first considered. Many of the posters expressed their concern about the lack of DM presence (and oversight) being a contributing factor in the boredom/slap-stick of the high level community, and really just in general.
So I'd like to propose a suggestion. I can understand that accepting new people onto the DM team can be a very sensitive matter, and while those that are currently running things are great, I think most of us can agree that there needs to be more. Obviously these people cannot be around every hour of every day - and no one is asking them to. DMing is, half the time, as much a job as it is a game. Since accepting people willy-nilly into a position of power and, at times, stress would probably cause more problems than it solves, why don't we meet in the middle ground?
Why not institute a second type of DM whose main purpose is to improve the atmosphere of the server. And I mean just dropping yellow text around or possessing the occasional NPC to help make the server feel more alive and authentic. It can be as simple as popping into Bianca and emoting her cleaning dishes behind the counter at the inn, or serving drinks and foods to guests. Or maybe Radu giving people the stink-eye as they pass. Or it can be ghosting along with people through a dungeon, adding flavor text here and there - like hearing the howling of wolves and seeing the occasional glint of their eyes reflected in the moonlight.
Honestly, it wouldn't have to be much, but even these small clips would do wonders. Not only would it improve the atmosphere, but it would make that mundane dungeon run that you've done a thousand times feel fresh and dangerous. It would give a voice to the NPCs that are generally ignored throughout the day, and it would certainly make people more conscious of their actions.
The ADMs wouldn't even necessarily have to have access to the DM forums. They wouldn't need to have a bunch of sensitive information that could, potentially, be used against the server by alienating players. And, if after a time an ADM proves trust worthy - who knows, perhaps they can get a "promotion" to full DMship.
Personally, I think this idea would solve a lot of issues. Improving the atmosphere and authenticity, giving NPCs and dungeons new life, and even adding a bit of oversight so that players aren't running around being silly and exploiting the lack of attention. Better yet, ADMs (if implemented) should be allowed to give out small gifts of xp to those they see making an effort to RP. Naturally there would need to be an application process for such a position, but since you wouldn't be handing too much power or sensitive information to them, I doubt it would be that hard to find people fitting the bill.
