I recieved my login and other hosting info by PM today, thanks a lot for it!
I wished to see how big an ad is required to show in the free account, so I powered up notepad and made a Hello World type page, added the script given in the PM, and uploaded it on my host account, but I see no sign of an advertisement, can anyone tell me what I am required to do?
Google displays ads depending on the context/content of your page. If your page is empty or if the google script didnt find any keyword which will work to display on your page, then it wont display any ads.
So please add more content on your page for google ads to be displayed.
