From Hubpages, you can go to "my account" and select the "affiliate settings" link under the Your account category. This gives you a list of all your adsense, ebay, amazon, Kontera accounts you have, with a link (Check Your Google Earnings) that takes you straight to the right page. There you type in your ID and password, and you can check everything. It's a one by one, but it's simple enough. I hope this is helpful.
