On the requests page, you will get a complete overview of all your open and already solved requests.
In the ticket details it is also possible to mark the ticket as "solved" on your own.
Please note that if you have opened up a ticket via email, it is necessary that you sign in / sign up, with the same email address. Otherwise, you won't see your tickets.
