Can I change my username or email?

Your display name, photo, and bio are yours to edit any time: Edit profile in Settings. That is the name shown on your profile and next to your listings.

Your username (the @handle, which is also your storefront URL) and your sign-in email cannot be changed from Settings. Write to support@papercranewholesale.com from the email on your account with what you want changed, and a person handles it.
