Grundsäin addition, it is possible to obtain information from my[fair]product without registering.
Users who also wish to rate contributions or responses from organisations must register with a user name and email address. Why?
Contributions and responses can be rated as "Convincing" or "Not Convincing". The ratings should give a realistic picture of the mood of the users. This is the only way they help organizations to recognize weak points, this is the only way they help other users to orient themselves.
However, we only get such a realistic picture if a user* can rate each contribution only once. This ensures that my[fair]product stores the ratings of all registered users* and that in addition a double rating of the same post or the same answer is not possible.
