Yeah so it's just a popularity contest right? None of you seem paticularily interested in figuring out exactly what your admins should be doing.
It's pretty bloody obvious. To give just a few examples - They oversee the moderators, deal with the structure of the forum and generally manage anything to do with the forum. They can't do that, nevermind more pro-active stuff if they are not here.
We don't need to define their entire job role between us. We just need somebody active and bright to take on the role and then they can look after it.
If my company appointed a new managing director, they wouldn't ask the guys in the factory to define his role. He would be able to come in and make the job his own in his own way. Effort, activity and ability is what we need rather than a limited checklist of admin functions.
