I just applied for this. Adsense Referrals Beta is the CPA version of Google adsense. How long will they take to approve you? How is it working out?
it took me a week or two, but they never sent me any notice that i had been approved - i just looked in my referrals area of the Adsense setup page and saw a bunch more stuff one day.. I havnt looked since then, but at that time (a few weeks ago) they did not have many referrals to choose from..
