if(!strcmp(cmdtext, "/newbie", true))
{
    new string[128], sendername[MAX_PLAYER_NAME], text[64];
    GetPlayerName(playerid, sendername, sizeof(sendername));
    format(string, sizeof(string), "[NEWBIE]: Newbie %s: %s", sendername, text);
    SendClientMessageToAll(-1, string);
    return 1;
}

That would be right I guess. Except that you don't have any "method" to read the params. So it would just send a blank message.
