I want to see a Featured Session, do I have to click on the "sign up" button?
You must click sign up/register. The button is accessible from the event post in the room (see: https://iftinfocus.ift.org/rooms/food-safety-transformation-infocus). The attendee will put in their email. Depending how far out you register/sign up you will receive a confirmation email as well as a reminder email 15 minutes before the start time. If you register/signup right before you will be placed in a waiting room.
