Ow... Thanks for reply InsiteFX...
Thats really help me to make more understand about code igniter class construction...

But.. How can I load About Us View? Is it load from Home Controller??

I want to ask one more question..

Whats the different about site_url, anchor, base_url...
I have read the user guide, but i still can't understand clearly...
Can you give some example?

Thanks before
