Login.php template file
From Shopp Documentation
This template provides the authentication form for handling account logins when the account system is used in Shopp.
It only activates when using an account system (with or without WordPress integration). By default it uses the account email address to identify the account to authenticate. However, you can customize this template to use the login name (username) instead. Shopp will transparently change how it processes logins.
Once a successful login is processed, the customer will be shown the account management screens handled by the account.php template file.
