Go to the JoyofSatan website and go to the section join Hells Army and read all of it.
Aside from that there's plenty things you can do. Go to yahoo and search yahoo answers then go to browse and go to society and culture- religion And spirituality and help spread the truth about God and what christianity judaism and Islam are about.
Be a gentlemen though because you will get banned from yahoo answers if you be rude or spam questions.
You can Also spread the truth on other sites but in reality this is weak.
It's better to do rituals against the enemies of Satan.
But we do need all the help we can get so if your not busy let's spread the word.
Hail Satan
