Those who answer in an AE thread will start getting AdSense share right away (even if their answers are under new submissions, waiting for review by the editors.) Based on points, the earnings are accrued. Suppose the total points for all posts together in a thread is 50 and you got 10 points in that thread, then you will get 20% of the impressions as your proportionate share. The remaining 80% goes to the other members who responded in the thread, provided they have an AdSense account. If any of them do not have an AdSense account, then their share goes to ISC.
