This website is public, everything you put in here is public as well, except the details of your user account.
When signing up you don't have to provide a real name or an email address, though this might make sense when you work here in the team. These details are only visible to the Server administrator and are not published, copied or given elsewhere.
When accessing this website - also read-only - standard webserver logfiles are being created (apache combined). These are only visible to the Server administrator and not shared with others. Every hour anonymised statistics are being compiled which are publicly available.
