i know that the lighting bolt is life but the others really baffle me not to sound posh tbqf its intresting, i would think if any of us fairly new would be drawn to it . and also (INOCHIAN) has some thing to do with it... ithink but any body who could fill me in on it a little i would be thankful .^_^
