It is a nice campaign with new feature of pay (pay per post + pay for keeping the banner) , but for how much time will you pay to members for keeping the banners in their footers? suppose a person do good quality posts and in a week he completes about 1000 posts (then his daily pay become $0.50, so you will have to pay $0.50 per day to him) and after that 1000 posts he stop to post from here for months or more then that, then will you pay him $0.50 even in this situation?

I think with that you will lose a lot of your money, My purpose is not retract you to pay members that amount but for longer survival I am suggesting you to plan a good idea about that issue, as it is going to appear in the future.
