For the people volunteering, do you really want the job? Seriously?
I admin a very big forum. Not the amount of unique users at MR but it is rather large. It is a major PITA most of the time, with very little respect given. You are constantly being questioned about your actions. You can never make everyone happy. You have to delete spam. You get constant PM's "can you change my user name", "this guy called me a name" yada-yada-yada. You have to deal with vindictive users who target others for nothing other than inflating their e-penis. It has literally sucked most of the fun out of that forum for me.
Seriously, the job is thankless and some of these people devote TONS* of their free time to make the experience better for all. But it isn't easy and it isn't a walk in the park. You will, ABSOLUTELY, be looked upon differently as soon as your status is changed and mostly not in a good way.

*getting a PM email on my iphone while I'm at the bar to delete spam. Yup, just what I felt like doing at the bar!
