Help!/Who admin's the admin's

From Tardis Wiki, the free Doctor Who reference

Hi

Im a new-ish contributor and a VERY dedicated fan - Possibly THE most dedicated fan there is, and I say that without arrogance since I JUST made a sonic circuit board (for my own in progress screwdriver) that CAN open (some) locks!!!! Seriously message me if you'd like to book a purchase once i'm whipping these screwdrivers out regular - I WILL honor first come first serve here lol! :P

But im confused as to the admin/moderator hierarchy on this wiki and the moderation policies? It's great that you nominate your own admins.......but IS this a fully unbiased process or do the current admins do the nominating/suggesting of new ones?! Also, is there a HEAD admin or some sort of hierarchy within the admin structure should a contributor have a grievance or debate with a single moderators decision?!

Since the Public use and trust all wiki's now as an unbiased source of validated facts I feel it is important to also publicize how the admins that review all imput are them selves reviewed to ensure a lack of bias (possibly with a formal statement on here?!) - Otherwise there is now way to know if the admins here are removing/creating relevant/irrelevant posts based on personal whims etc.

I'd appreciate everyone's thoughts on this. VERY keen to make this a good wiki and feel the best way to do that is to make it FULLY unbiased and open minded to ALL -non spoiler- topics of interest. AND..... more importantly, to let the PUBLIC know HOW we achieve this!!!
