am always around, like i said havent got the files set up to test anything i tell you. but the is a way to make an admin make sure the char is logged in, and on your gm char type @SetPermission <Uservername> <Permission level(0-10)>
set there permission level to 5.
to change what commands they can use. in your m2server.exe click server Options > Send Game Command
and change the permission on the commands you want them to use to 5.
like i said there might be an easier way to do it maybe in admin.txt have it ** username
and the way i told you i'm not sure if it resets there permission upon reboot/logout. give it a try
