hi, may be a silly question, but is it allowed to "stack" 3 small (this 1 ad 120x60) blocks to let them look like a skyscraper? im just asking because its for revenue sharing (so 3 different pub ids), and i really hate it to see 3 large google adspaces in each corner...
You can't have 3 pub ids on the same page to my knowledge. You will have to rotate the pub-id using a php script.
