If you are new to Joomla!, you probably are wondering how Joomla! can be used to build a Web site. Even for a Joomla! veteran, sometimes it helps to get inspiration from other people's work.
Joomla! Community has started a showcase for Joomla! users and friends to register sites built with Joomla! by themselves or found on the Web. Sites are grouped into various categories so that it's easy to find a site similar to the one you have in mind. Studying those Joomla! sites can help you see how different components and modules fit together and what work well in the specific situation.
So why don't you go to Joomla! Community Showcase now and browse around? You might find some sites worth visiting.
