Hello, I see that you have removed some of the references from Gordon Korman. You have identified those references as a "pay to click website". Could you please tell me what that means and how you identified that page as such? Also could you please tell me what wikipedia policy the use of such sites violates? Thank you. 75.69.0.58 (talk) 16:14, 14 October 2009 (UTC)
