With just one word in the city where you reside you should be able to retrieve information about products, services, companies, events, etc...
Information you get comes from people managing those words, and interested and confident enough to leave information pertaining to words they manage on the VisionAfrique servers.
Obviously VisionAfrique is not all things to all people. Information about words (products, services, companies, events, etc...) not stored on the VisionAfrique servers cant be displayed.
