Mousumi, you are not the only one but everyone has this issue. Admin has omitted to credit earnings for the three weeks you mentioned for everyone. There is no question of your being not eligible at all, simply an omission on his part. Let us wait for his response on this!
Thanks for your reply Kalyani. I know that none of us have been credited earnings for the past three weeks, but since I had mentioned this in another post,which was started by Maverick to inform us about the ugradation of the site, I thought it is better to re-highlight this query under Help category. Since he replied to other post in that thread and skipped mine, I was forced to think I have raised a query in the incorrect category.
