For previous years' campaigns, it will depend on which year you've backed.
Your rewards will be in a specific URLs for each campaign, which you can find at http://www.rifftrax.com/backer
- clicking on an individual link will take you to the Rewards page for that campaign, where you can "authenticate" your account by entering the e-mail address you used on Kickstarter
at the time you backed us, and submitting the form.
If you're not sure which email address you used, visit your Kickstarter account here
, or visit the campaign page and click the "My Pledge" button.
