Like: i am the user of webwave, and right now the only way to sell my site/template is to provide my site as templates in webwave. It would be more intresting if there is a whole marketplace where creative users can share there sites and sell it there desired price, that way users can earn extra money too.

A person who need sites will pick the best sites that fits his desire and pay money, and a template owner will earn some extra cash by providing the site.
