I suppose you can rent your ads spots at Services section of the forum or maybe should it be posted at Service Announcements?

Someone with a better interpretation of forum sections could enlight me, please?

Anyway, I always see faucet owners renting ads spots on their own faucet main thread... Although I understand you may want to attract more attention than you usually receive at Micro Earnings tab, as the traffic of forum members there is usually lower, especially when compared to Services section.
