User blog comment:Sannse/Important Updates on Wikia’s New Look/@comment-2173759-20100929120536

In the new version of Monaco, the content area will move up, replacing the top area that had the banner ad. For logged-in users, article pages will have a 300x250px ad unit, floated to the right. Pictures and infoboxes that are floated to the right will automatically move below the ad. The ad units will be added automatically, and won't appear in the editable wiki code.
