I'm having trouble managing the main page of this wiki. It is supposed to be like next:

upper messagebox left column right column

Yet I noticed that there is an ad that pushes the layout downward:

upper messagebox ad  left column right column

So it should appear broken to non-registered visitors. I would like to fix this without having to delete or reduce the upper box. Can anyone give me a suggestion?
