I recommend signing up for the email to be safe, that process worked well yesterday and if you accidentally close your window it should be a good backup.
This should be the link to share queues (copy/paste the queue ID after the = sign)

Note that yesterday I ran into some issues with using a shared link, and then when it was my turn I got dumped on a landing page, and when navigating back to the special events page it gave me a message that the link had already been used. When I was successful, what I did was log in (or log out and then log back in) on the landing page, and then it should take you to the ticket purchase page. If you skip logging in you will get the error. The tickets I bought were from someone's shared link so I know it works, it's just not as straightforward as usual since the login step is key.
