Liability claims regarding damage caused by the use of any information provided, including any kind of information which is incomplete or incorrect, will therefore be rejected.
All offers are not-binding and without obligation. Parts of the pages or the complete publication including all offers and information might be extended, changed or partly or completely deleted by the author without separate announcement.

2. Referrals and links
The author is not responsible for any contents linked or referred to from his pages - unless he has full knowledge of illegal contents and would be able to prevent the visitors of his site from viewing those pages. If any damage occurs by the use of information presented there, only the author of the respective pages might be liable, not the one who has linked to these pages. Furthermore the author is not liable for any postings or messages published by users of discussion boards, guestbooks or mailinglists provided on his page.

4. Privacy policy
If the opportunity for the input of personal or business data (email addresses, name, addresses) is given, the input of these data takes place voluntarily. The use and payment of all offered services are permitted - if and so far technically possible and reasonable - without specification of any personal data or under specification of anonymizated data or an alias.

This disclaimer is to be regarded as part of the internet publication which you were referred from. If sections or individual terms of this statement are not legal or correct, the content or validity of the other parts remain uninfluenced by this fact.
