Solanales; Email me (firstname.lastname@example.org) from your Kickstarter/Paypal email address, with the forum account (user name or email). I can search the backer database and enable forum badges if the Kickstarter/Paypal and forum email match, but I can not search the email addresses entered in the Vault.
