[quote author="inparo" date="1215059389"]The keywords here are "through index.php". Index.php is the default entry point, but it does not have to be.[/quote]

So I can have multiple entry points, like blog.php for a blog section, with it's own models, views, and controllers and a forums.php for a message board section with its own models, views, and controllers and so on?
