hi, i registered to DP coop today. I have 3 questions 1. Do i have to paste an ad on my website (like a reciprocal link?)? 2. Can i submit multiple Urls for 1 website? 3. When i registered for Google API key, there's the API key, and another long code that starts with <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" Code (markup): and ends with </html> Code (markup): generated. The key i used in registering for coop. Where do i use the other code? TIA!
