I agreen with what above. However, a COWOA has to input the email address and if after one year he comes back and try to login the login will be refused. He may then try to get a new password thinking he forgot it. He gets an email with the new password and then the login will be refused again. The COWOA will think ths site is broken and will go shopping somewere else. I think the COWOA, when tryng to login should receive a warning message saying "We know you purchased with us using this email ADDRESS, but you choose to not create a account. For your privacy, this is not allowing you to receive a new password neither to login with this eamil address. Please buy again without account or create a account if you like." Even better the essage should finish with " If you want to trasform your guest purchase in a account puchase click here and you will receive a password, at the email address used in the past, to login with that email address and make your purchases." Obviously the COWOA has to became a regular account in the db.
