If you start a $5 (or higher) monthly membership, you will get the details on how to access all of that fun stuff on your confirmation page and in your confirmation email. Or, if you're already a member at the $5 level or above, you'll have gotten an email from donations@maximumfun.org with the new details. Check your spam folder and promotions tab if you don't see it in your inbox. If you're still having trouble gaining access to the bonus content, you can always email donations@maximumfun.org.
