it says my ads are shown 50% of the time when i start a topic, so the 50% of the time whos ads are shown, DP's or other members? and when we reply to a topic, what % are my ads shown? might sound really dumb but i'm all confused :S
I think your ads are shown only for the thread you started.50% times the ads of the site owner are shown(whichever publisher id he uses).
