personally, i dont like any of these, no offence, here are types i thought of...
Host - (for dedicated servers) makes ONLY ONE PLAYER host (only useable while host, so you can make youself auto)
sub-host - a player that becomes host when the real host leaves, and vice versia
GM (game master) - the lowest admin
anti-admin - player cant guess the admin password
anti-admin = rank 0
GM = rank 1
admin = rank 2
super admin = rank 3
sub-host = rank 4
Host = rank 5
(i forgot this one...) Badspot = rank (cannot calculate due to rank over 999,999,999,999)
