I have a blog on blogger.com i also have google adsence on it. The thing is that I don't know if I am being paid per click or not. For that matter if my adsence is working or not. A few of my friends had a request from adsence. I never waited for the request and managed to get adsence ads on it. Till date i havent received any mail or notification from them.
I not sure whether you are approved by adsense. Please go to google.com/adsense and log in If you able to log in then you are approved and start earning with adsense.
