Adding an email address at payment time shouldn't update the email address in the patron record

[Kathy Lussier]

When paying by credit card in the public catalog, there is a box that displays the email address from the patron record with an option to update the email address. When the email address field is filled out, a receipt will be sent to that email address.

However, the option to update the email address assumes that the user wants to update the address in the patron record. It's possible that the user just wants the email receipt, but doesn't want to change the email address on the account. For example, if a parent is paying off charges on a child's account, they may want a receipt emailed to them, but may want to keep the child's email address on the record.

The mail box on this form should either a) only be used for the purposes of sending an email receipt or b) include a checkbox option to update the account email address.

Also, I'm unclear as to why this field needs to be disabled for text entry with a clickable Update link to make any changes to the email address.
