Back to Class
Since Classic, one guide per class, and nothing you already know.
Tap your class and leave an email. One message when its guide is up, with the link, then nothing.
Tap your class above, leave an address, and the link comes to you the day the guide is up. Nothing else unless you ask for it.
You confirm with one click in the first message, and that link is also how you change your mind later. Your address stays on this site's own server and goes nowhere else. How it is kept.
What changed since Classic, and nothing you already know.

Every class gets the same treatment, in the order the video tells it.
