There are over 100 hours of bonus content - extra episodes of shows that hosts record just for members like you. What does that include? All kinds of stuff! Behind-the-scenes episodes, one-off ideas, crazy cross-overs; sometimes they throw in some extra live shows or videos, too! They're accessible to anyone who is an active monthly supporter at the $5 level or above.
If you start a $5 (or higher) monthly membership, you will get the details on how to access all of that fun stuff. Or, if you're already a member at the $5 level or above, you'll have gotten an email from firstname.lastname@example.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 email@example.com.
