Banners could be areas of the screen of a certain size that show different information randomly, such as advertising banners.

In a system with lots of banners, some may have more priority than others. One banner might be shown at the rate of 10 times per 100 and another might only be 1 time per 100. Each banner needs to be setup with a priority list.

Optionally, the banners could be setup based on the committees that someone belongs to? The foundation committee members may see some banner ads that others don't see? Just an idea, don't know if it's feasible.
