The Opera browser is fully customizable depending on each school's particular needs. For example, a university can use its school colors and mascot in the design of the browser's buttons, backgrounds and borders comprising the user interface. The Opera browser also features a communication banner where the school can insert news or other announcements for its students. This feature can be used as a line of communication between the school and its students.
Pretty sweet stuff there. I guess the "communication banner" is the same as the "ad banners" you get from the free version.
