On your home page, there's a Tickets button along the left column of black buttons - click on it to start a ticket.
If you want to create a ticket on a specific hearing, simply go to that hearing and click on the "Create Support Ticket" button at the top.
Then fill in the required sections and Save. (Note: the Category section is the intended recipient - i.e. if you want help with an issue on the website or technical problem, click on "Tech Support" in the category box.)
