LoL, so you want an admin system? Just look on filterscripts section, there are alot of admin filterscripts, if you can't make your own, download one!
EDIT:
Buuut. You can make a level system:

pawn Код:

new gPlayerLevel[MAX_PLAYERS];

pawn Код:

public OnPlayerConnect(playerid) {
    gPlayerLevel[playerid] = 0;
    return true;
}

And, if you want to set player's level:

pawn Код:

gPlayerLevel[playerid] = somelevelhere;

And, to make cmds only for some level:

pawn Код:

if(gPlayerLevel[playerid] < 2) return SendClientMessage(playerid, 0xAAAAAA, "You need to be level 2 to use this");

Will make a cmd for level 2
