How to generate a report of users who have created an account but have not purchased a ticket

Is there a way to generate a report of people who have created an account but have not purchased a ticket?

To find a list of people who have created an account but have not purchased a ticket in Dryfta, navigate to People > Manage Contacts in the administrator dashboard. 

Use the advanced filter option, select the 'User Roles' filter, and then set the condition to 'IS NOT' and choose 'Attendee'. This will filter and display all contacts who do not have the attendee role, i.e., those who have accounts but haven't purchased tickets. 

You can then use this list to confirm registration status with the individuals.
