To make this simple for some ignorant people, who gave you the code for LiveJournal?
If nobody gave you a code.. you bought one yourself, then the question will be: Where did you hear about LiveJournal from?
s2sugarcoateds2 sired me. In a chatroom, she was talking about her LiveJournal, and at the time I have never heard of a LiveJournal and I asked her what one was. She introduced me to the LiveJournal world, and I fell in love with it, and begged her for a code. Thus I was made! ;o)
