Sometimes people seem to be unsure on where to draw the line, so things can be confused/forgotten or administrated vaguely in certain cases.
A dedicated team could solve issues related to the above.
Often when it comes to reports, even those that can view/administrate them may "let them go", unsure on the best actions to take and/or unsure whether they should be the one managing it.
Punishements may also vary, depending on who issues them. A uniform system would be the most advantageous, and it would save the Owners, Community Leaders, Division Leaders etc. having to manage the majority of the things.
Another interesting 'tool' might be a section that allows users to report minor issues (perhaps not necessarily rulebreaking), move/lock requests etc. The report function could be made use of here, but in certain parts of the forum this could be counted as an out of purpose use for it.
I think the more these forums expand, the greater the number of users more the demand would be for this idea.
Edit: As I posted this and went to view the Forum and site ideas board almost immediately ran into 2-3 newer topics that should be in other boards. It would depend to what extend things would be administrated on, and how closely people are to keep to any forum guidelines.
It's good that we have a well rounded Argonath RPG Administration "unit". If a Forum Admin Team was required, a handful could more than likely be chosen from existing A-Teams.
