Add an email to a fixture

When you wish to give some free access or add some should there be some issue with payment you can add a persona email to a fixture.
Shown below "Add email for this video stream" input box, allows you to enter the email in the input box and press the ADD button. (you can ignore the tick for overseas for now). Note you will need to delete the email in the input box to allow another email to be added.

When you then view the Purchase tab you will see that user listed.
