You are very correct. I missed the great forum.. I could have joined early. But can't I win this month - March?? Or this contest is just for the last month?

I am not really sure about it..! I am not getting much time now to be more active but really a good forum to earn in short time. thanks for your wishes.
No, you can't win this month. Only those members who register in this month are eligible for the prize. Anyway, still you have earned a lot, so it's not bad. Keep it up, and I'm sure you will earn more.
