It challenges the server by it\'s IP using the RCON protocol, using that it sends it along with the rcon password and the command to execute when you try to send a command. It was made to almost mimic the real console (text-based) in half-life, which is why I didn\'t make a dialog for it. You can change game settings with it and also view the live logs of what is happening in the server (e.g. player 1 killed player2 with gun).
What version of mIRC are you using? Also tye\'s independant review needs to be updated since you can now add/edit saved addresses in the latest version ;)
By the way, I forgot to mention how to use this. For those of you who are unfamiliar with aliases, type /hw to hide your query windows, and type /uhw to unhide your query windows. Enjoy!
