Limitation of liability
The contents of this website have been created with utmost care. However, the provider cannot accept any liability for the provided contents being accurate, complete and up to date. The user accesses and uses the website contents at their own risk. Any contributions identified by name reflect the relevant author’s opinion which is not always the provider’s opinion. The mere use of the provider’s website does not establish any contractual relationship between the user and the provider.

External links
This website contains links to third-party websites (external links). The relevant operators are liable for these websites. The provider examined the third-party texts for any legal violations at the time the external links were first linked. At that time, no legal violations were apparent. The provider has no influence on the current and future arrangement or contents of the linked web pages. The placement of external links does not mean that the provider identifies with the contents to which the link or reference is directed. In the absence of concrete indications of any legal violations, continuous monitoring of the external links is unreasonable for the provider. However, such external links will be deleted without delay if the provider becomes aware of legal violations.
