Newbie - Setup and URL Questions

[eluser]joshdrew[/eluser]
I set up Codeigniter..left everything pretty much default. I was able to create a few pages and registration forms and so far so goo. My question is regarding urls and templates.

I have a mysite.php controller file. this performs the necessary functions to pass variables into my view pages to get the right content for my template.

ex:

Code:

function about() {
        $data['main_content'] = 'about';
        $data['page_title'] = 'Welcome to Diary 90';
        $this->load->view('template', $data);
    }

I have a template file in views that pulls everything together

Code:

$this->load->view('includes/header');

$this->load->view($main_content);

$this->load->view('includes/footer');

I then added a default controller called "mysite" to the routes config.

if I go to http://mysite.com I get the index page. Great.
if I go to http://mysite.com/mysite/about I get the about page. Ok.

Questions
1. How can i get the about page by just going to http://mysite.com/about. I can do that WITHOUT templates but not with one. I must have something set up incorrectly.

2. If I wanted a "members" area like http://mysite.com/members/index how do I set that up? do I create a subdirectory in the controllers dir called members?

Thanks.
