We would love to be able to allow some of our super-users to be moderators of certain forums. They would be just like normal end users but would have the ability to administer certain forums.
In much the same way as we can limit forums to only agents, there should be a setting for "Only agents and moderators"
Moderators should be able to create, delete and add comments in their designated forums.
Apart from that, no other special permissions should be granted.
