Feature summary (what you would like to be able to do and where): I would like to be able to sort the registrants in an event by column.
Use case(s) (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution): When I look over the events registrants, I want to see the different levels of skills and user group names, by putting them in an order I can parse quickly.
Benefits (why should this be implemented?): Make it easier to target individuals when messaging them, or to look at specific user profiles.
