I can't understand wow to apply changes to include advertise in my main page. Has a strange structure... for this reason I didn't manage to! I unblock the page... can you help me? http://it.squadraspecialecobra11.wikia.com
To make the main page be formatted so that ads don't mess it up, you have to use the main page column tags in the coding and all of your content has to go in either the left or right column. See these help pages that explain how to set it up:
Ah... i see my page in a different way... All elements (included the "welcome box" that you see in part hided by ad) shift down. In other words, i seen in the top-right corner ad, and the space to his left stay empty.
Anyway i would include ad in the right column, but I don't manage to...
