When you create an account (optional), you create an Email and password (see Registering an Account).
With the upgrade of the shop, we required that all customers re-activate their account, and create a new password. If you had an account but missed the re-activation email, contact support and we'll resend it.
Editing your account
Customers can easily edit an existing Address, or create a new one.
Select: Account > Edit: Then modify your details.
Change email address
Currently the system doesn't have the facility for customers to update their email address. To change your email address, please contact support.
