Option to choose how a name is displayed

The registration form allows users to register with their first and last name and also provide a nickname. It would be useful to let users decide which name should be displayed publicly — their first and last name or their nickname.

Nowadays, more and more users prefer to use a nickname online, while from a business perspective, having the user's real first and last name is still necessary.

Therefore, it would be great if users could choose whether their public name is displayed as their real name or their nickname, while the first and last name remain available for business and administrative purposes.
