There should be a "Staff List" button on the Menu. In this, it could either show all the staff like beforehand, or just the GPs (which is most useful). Then it'd be accessible everywhere rather than just the kiosk.
You could even go another step further and add an "add staff member" and "pm staff member" button when you press on their icon. Then we wouldn't have to search the Player Database for a staff member which was difficult enough. (Or when you press on their icon it just opens their profile so you can add them and pm them as you please).
Not much development is needed to add this, as we already have a friends list gui which could be filled with the current staff when you press on the Staff List button. And we already have the profile GUI and all that junk
Rather than adding back the staff list (which is needed) go ahead and improve it.
