Dear Slav2 and Team,
I have a video on ratting from You Tube. You can do it at any level but yes low sec is the most profitable. Gold Harvest has fully automated setup and execution thats why I love Simple Miner. There are other ratt program bots but they have a lengthy glitchy and tedious setup procedure that has to be done everytime you install the program.
Anyway here is the video from You Tube.
