It's better to be a genius than have someone help you look like a genius since just looking like one will more than likely have you looking like a fool in the end.
Be a genius: Hover over "About" in the main navigation menu, click on "What is moodle?" and read that page. When you finish reading that page, click on all the links at the bottom of the page and read them too. I guarentee you that you will not only be a genius in no time, but you never be anyone's fool.
