[rt-users] Searching Unprivileged Users

[Sysadmin]

Currently we have RT configured so that support staff are privileged 
users, and customers are unprivileged users which Are also part of the 
"Customers" group. I'm look for an easy way to search the unprivileged 
users, RT only shows privileged users, and groups only let you add or 
remove users, not edit the users in the group.RT adds the unprivileged 
user from the ticket creation. So it is very easy to accidentally create 
a bogus user in the system that is simply created as an unprivileged user.

Thanks,
