Link structures

[eluser]Jmz[/eluser]
I've been reading up on CI and I think I have the basics, but there's one thing I can't work out about the link structure.

Say I'm making a blog where a user has an admin panel and an add page option. My class for the admin panel would look like:

Code:

Class Admin extends Controller{
    
    function Admin(){
        parent::Controller();
    }
    
    function Index(){
        //Do something    
    }

    function Add_page(){
        //Do something    
    }

}

If I go to mysite.com/admin it does whatever is in the Index function. If I go to mysite.com/admin/add_page it does whatever is in the Add_page function. Makes sense.

What if I want to change the link to mysite.com/admin/pages/add_page so that it's more organised? Can I do this?
