*Another admin? No
*Giving some mods extra commands after making *absolutely sure* that they're comfortable with them? Sure
Waypoints and chests are the ones that come to my attention on a usual day.
I only recently discovered that you couldn't roll back any privated chest, which has made my job slightly harder. When before, I could assume, after a week or two of being hassled to move your house, I could go ahead and rollback everything, including the chests; now, that doesn't appear to be the case. Maybe if rollbacks were to exclude chests, or if we were able to, say, "unselect" a region in worldedit, this would eliminate the issue. For instance, select the entire house, then go inside and deselect the chests&private signs; thus, worldedit would affect everything around those chests. This would make it so a mod doesn't have to rollback tiny bits of a house, individually, in order to remove a shack with a private chest full of stone tools and dirt...
Waypoints, I can see as a potential command for select players. They would need to be handpicked by Zerg, since he's the judge of whether a town qualifies for a waypoint. This also carries with it the inherent dislike from players who you simply can't give a waypoint to, due to their town not looking, well, 'pretty enough' for a waypoint. But it's something to be considered.
As for chest recovery; I could also see this as something we can trust a few more mods with. Of course, they would have to be given a VERY thorough explanation of how it works, and be able to prove they can do it, without any doubt, before being given the command.
Edit: I somewhat agree with Hovr's concept, excluding some of the commands mods should be given. However, I don't think the mods who have been given these extra responsibilities should have any separate rank than [Mod]. So I chose "No."
