It is optional to share your address, telephone number, and more with the project. This is mainly helpful for people who are deeply integrated into the project, but you can of course fill in those fields so that we get to know you better.
This information will only be shared with the IPFire team and won't be publicly visible.
If you go to your profile and edit it, you can enter a "Nickname" which will be shown instead of your first and last name. We would still encourage you to keep your real name in the database.
