Now that I have created an account how do I register or sign up for the eshadowing?

I’m trying to figure out how to register for the eshadowing on the 20th of next month but when I click the link it says the webinar expired. How do I make sure I register before that date, especially when the eshadowing portion of the website does not let me even enter my email to notify me when the eshadowing is happening or coming up. Please help. I really need help registering for the shadowing, the FAQs about this are vague and I’ve already been trying to do it for an hour. Please help make sure I can get into the next eshadowing!

Thanks,
Cat Cutrone
