if(!strcmp(cmdtext, "/me", true)) // 3 is the length of /me
    {
        if(!cmdtext[4]) return SendClientMessage(playerid, 0xFF0000FF, "USAGE: /me [action]");
        new str[128];
        GetPlayerName(playerid, str, sizeof(str));
        format(str, sizeof(str), "* %s %s", str, cmdtext[4]);
        SendClientMessageToAll(0xFFFF00AA, str);
        return 1;
    }

It should really start from the 4th character, because players could simply do "/me " and the command would still be processed.
