Notice of Liability:

1. Website content :

The author himself and the information providers are continually trying to provide high quality information. The author nevertheless does not assume any liability concerning the topicality, correctness, completeness or quality of the information provided. Any liability claims against the author, which refer to material or non-material damage, and which may have been caused by the usage or non-usage of the information provided and by the usage of any incorrect or incomplete information, respectively, is principally excluded, unless there is willful intent or gross negligence on part of the author. All offers are subject to change and non-binding. The author expressly reserves the right to instigate modifications, amendments or cancellations of the website, in whole or in part, or to discontinue this publication without any prior notice, either temporarily or irrevocably.

2. References and links:

In case of direct or indirect references to other websites (hyperlinks), which lie beyond the sphere of responsibility of the author, he will only assume liability in the case of the author having knowledge of the con-tent, and it having been technically feasible and reasonable for him to have prevented its use in the case of it having unlawful content. The re-spective supplier of those pages, and not the operator of a different web-site who merely provides a link to the publication in question, is exclusively responsible for the content beyond the operator’s control and particularly for any damage that may arise from the use or non-use of the respective information offered on these pages. These limitations equally apply to third party contributions to the guest books, discussion forums and mailings lists provided by the author.

3. Copyright:

The author aims to respect the copyrights of the graphics, sound files, video sequences and text used in all publications, to use graphics, sound files, video sequences and text created by himself or to resort to public domain graphics, sound files, video sequences and text. In case the corresponding pages still contain graphics, sound files, video sequences and text, protected by a third-party copyright but not designated as such, the author was unable to determine the copyright. In case of such an unintentional violation of copyright, the author will remove the object in question from his publication immediately upon notification, or he will add the appropriate copyright notice.

4. Legal validity of this liability disclaimer:

This disclaimer is to be considered an integral part of the website in whose context it appears. In the event that individual parts of or formulations contained in this text are not, or are no longer, legally valid (either in whole or in part), the content and validity of the remaining parts of the document are not affected.
