Cisco :: WS-C2960-48FPS-L / 3750G - Creating Additional Logins

we have a setup of about 14 WS-C2960-48FPS-L all running from a 3750G stack.What i want to be able to do is create dedicated accounts so that local IT admins can tag ports via CNA without calling me everytime something needs to change. How and where can i create these on CNA? Is it as simple as using the Users and Passwords options?What privledge level should i assign to these accounts so that it will give the least amount of previledge required to tag ports. I dont want them being able to change much else.
