You just post on one of Czar's threads of which bot you would like, you download the client and start it up and as soon as he has activated your trail it will be on the bot, you don't have to download anything ETC. Just figure out which bot you want find the thread and post on it saying "Czar crabs please" ETC I have been running his bot's and I would recommend you to purchase which ever bot you would like, his scripts are flawless!
Also Czar check your PM's brother!
