Admin Question

First, let me tell you that the forum program is great and I will purchase it. I work inside a government facility and will be using the forum for employees only. I want employees to go through a moderator to register(got this one figured out). My delima is I want the moderator to be able to register employees and not be able to see all the Admin functions. I can't find a setting to do this. I see that it's and Admin option but don't want to give the Admin authority to all moderators. Any ideas on how I can do this.
