here is what i meant

pawn Код:

public OnPlayerText(playerid, text[])
{
    if(PlayerInfo[playerid][pAdmin] >= 1) //Change to your admin variable
    {
        new str[128], name[MAX_PLAYER_NAME];
        GetPlayerName(playerid, name, sizeof (name));
        format(str, sizeof (str), "[ADMIN]%s: %s", name, text);
        SendClientMessageToAll( -1, str);
        return 0; // ignore the default text and send the custom one
    }

//all other players will just send as normal...
    return 1;
}

now you wont cut the name and even use inline colors if you like to stand out.
