i not getting any money

You need to respond to more posts by other people. You need to give detailed responses than answer the question with helpful advice and you will earn more. I find I earn about 1.5c per answer, so if you want to earn more you need to work harder.

set a goal of making 25-50 discussions a day.give lengthy responses.dont answer in a single line.Try to reply to discussions that are following the guidelines of mylot.otherwise your post to that discussion may be deleted.Give quality reply to get best response from the starter of the discussion which will eventually increase the earnings for a post.start good discussions which will attract lot of responses.

I agree that 4 cents is not much for 21 points. I am probably just repeating what others have told you, but you need to post quality topics and responses of at least 3 -4 lines. Your earnings are based on the quality and the length of your responses. You should also try to add new friends to you list, as these will help to increase your earnings by responding to your topics. If at all possible, and I know it's difficult, try to get some referrals, as you will earn more based on what they earn. Also try to post as many responses as possible each day and it won't be too long before you see an increase in your earnings. Best of luck and I hope you will soon be earning more.
