I found this e-mail from this url http://forum.abestweb.com/showthread.php?t=77614 Is it real ? They told about "AdSense CPA Beta Discontinued" Dear XXXX, Thanks for participating in the AdSense Cost-Per-Action test. We'd like to announce that we're ending this phase of the beta. Therefore, please take down any CPA ads that you are currently hosting as there won't be any further support. If you'd like to provide us with suggestions or are interested in still being a part of such tests moving forward, please reply to this email. Feel free to respond with any other questions or concerns you may have. Again thank you very much for being a part of this test. Sincerely, Christian The Google AdSense Team
