i 've just found out this is ad revenue sharing forum I just want to know if i add my google adsense id now, will my old post's Ads change?
I read somewhere that admin of dp was first to start this concept "ad revenue sharing" websites. Oh your question yes as i understand it would display your ads where ever you would post..
It only shows in threads you start, you've 50% chance that your ads would be displayed in that thread. Read more details here.
It can be for posts within a thread too... http://forums.digitalpoint.com/faq.php?faq=revenue_sharing
Your adsense can show in a thread you started or when somebody looks at your post individually, such as http://forums.digitalpoint.com/showpost.php?p=723852&postcount=11 It does apply retroactively. Maybe a McChicken in your future.
