Sounds like a good start. People are going to point out the semantics of the impossibility of becoming a Satanist, but we know what you mean. We all discovered what Satanism was about from outside ourselves. Welcome to the boards. I will make the suggestion, if I may, to read the information at Church of Satan
to get better aquainted with the common language used among Satanists. Some people read into things a little too much, to be honest with you, when someone says they "believe" something for instance. Some consider it a little bit disrespectful to misspell Anton Szandor LaVey's name or addressing him by his last name only, to give you a head's up.
