Just some simple, short informative texts on the site, to inform new users about features, what they do, how they work and what they are for. Since a new user's account is empty, there is a lot of potential space.
For example: When you click on the dropdown menu and go to tickets, tell the user what tickets are and how they work. Or explain how the characters feature works.
This should give new and inexperienced users a better overview, a good first impression and can help to experience the site and its features more easily.
