On completion of your course / degree, you may wish to retain the padlets you have created on your OCA 'backpack' account. To do so, they can be transferred to a 'vanilla' account for use outside of OCA when you no longer have access to your OCA email address.
See the How do I sign into Padlet? article for a brief explanation of 'vanilla' and 'backpack' accounts.
You will first need to create a Padlet - padlet.com - account using your personal email address. Once you have set up your own account, you will need to contact Padlet using the 'Contact Padlet' Form available on their website; remember to include as many details as possible when completing the form. The Padlet support team will be able to complete the export process on your behalf, essentially transferring your padlets from your OCA account, to your new personal account.
