I'm not sure why you changed rcon password, but without it, we could not even kick a wallhacker that connected to the server and was ruining all the game. Without mentioning our unability to change map or put a password. What's the point of wasting your time in this "practices". I can just join some pub with same results.
Can you at least tell someone, two or three people, the rcon password so people could actually be able to make the time-wasting productive and interesting.
