1. Content of the online service

The authors cannot guarantee the currency, accuracy, completeness or quality of the information provided. Claims against the authors that relate to material or immaterial damage that was caused by the use or failure to use the information provided or by the use of inaccurate or incomplete information are excluded as a matter of principle, provided that it cannot be demonstrated that the authors are guilty of wilful or grossly negligent action. All offers are subject to change and are non-binding. The authors expressly reserve the right to change, add to or delete parts of the site or the whole service, or to suspend its publication temporarily or permanently.

 2. References and links

In the case of direct or indirect references to external internet sites (“links”) that lie outside the sphere of responsibility of the authors, liability can only be accepted if the authors are aware of the content of such sites and if it would be technically possible and reasonable to prevent their use in the event that they publish illegal material. The authors therefore expressly confirm that at the time at which the links were created the linked sites in question did not contain illegal materials. The authors have no influence over the current or future design and content of the linked sites. They therefore expressly disassociate themselves herewith from all content of linked sites that has been changed since the links were created. This statement applies to all links and references in their own internet service and to external entries in guest books, discussion forums and mailing lists set up by the authors. The providers of the sites to which reference is made are solely liable for illegal, inaccurate or incomplete material and in particular for damages that arise as a result of the use or non-use of information presented in this way; those who simply make reference to the published material in question by means of links cannot accept any liability.

3. Copyright and Trademark Law

The authors have made every effort to observe the copyright for the graphics, sound files, video sequences and texts used in all publications, to use graphics, sound files, video sequences and texts created by themselves or to draw on graphics, sound files, video sequences and texts that are not under licence. All of the brand name and trademark rights specified on the internet site and, as appropriate, protected by third parties are subject without restriction to the provisions of the relevant trademark law and the rights of ownership of the relevant registered owners. The conclusion should not be drawn from simple mention of a brand name that it is not protected by third party rights! The copyright for published items created by the authors themselves remains exclusively with the authors of the site. The duplication or use of such graphics, sound files, video sequences and texts in other electronic or printed publications is not permitted without the express consent of the authors.
