The Rialto component is a Classified Advertisements component. Wikipedia defines Classified advertising as a form of advertising which is particularly common in newspapers, online and other periodicals which may be sold or distributed free of charge. Advertisements in a newspaper are typically short, as they are charged for by the line, and one newspaper column wide. An advertisement as seen in a newspaper, magazine, or the like is generally dealing with offers or requests for jobs, houses, apartments, used cars, and the like. The Joomla component permits a site to accept such advertisements from its registered members and acts as a conduit between purchaser and seller.
