It was a brilliant day with great support from friendly people. We learnt a lot with all kinds of details. Another important factor was that among the adsense people was someone from the search team. In response to questions about Panda and add placement (especially over the fold) the answer from both adsense and search reps was that there is no problem placing adds over the fold as long as you have content on your user friendly page, and not just a couple of words and adds all over the place.
In a few words it was an enlightening experience, personally it made me feel that I am a part of this great company even as a small publisher. Again thanks to all the friendly people of Google and the great experience they gave us.
