Our server is running a standard instance of the apache web server. This is keeping the default access and error log-files. These are evaluated on a weekly basis to get an impression of the relevance of the Wiki in a global sense. That means we are evaluating collected IP adresses to see where our readers are located.
Besides that the only privacy relevant information that is collected about our users is the information they are adding to their personal users page. There the only expected data is the Real Name which is used to refer to the user everywhere in the Wiki.
