As answer to
this request, this is a modified version of Antithasys' fixed one adding a /adminon and /adminoff admin command so admins could hide themselves from the adminlist ingame if they want to act stealthy
This only hides them from the !admins list and doesn't touch their permissions at all.
Commands:
sm_adminon, sm_adminoff
Both require the generic admin flag.
(Also replaced GetMaxClients() with MaxClients)
