Liability for External Content

As a matter of precaution, we think we need to state the obvious:

  • We strive to make links to foreign websites open in new tabs or windows, so you should not mistakenly believe you were still receiving such content from our website.
  • When we provide a link to a foreign resource, we do this in good faith that the provided link and link target was legal at the time we added the link to our website. Of course, we typically have no control over foreign websites whatsoever, so if the linked-to content may be illegal at some point, or unavailable, that should we well outside our realm of power. If you encounter such a situation and think this must be rectified, please notify us, and we will see what we can do about it. In the worst of events, you should feel free to abstain from viewing content that you deem unsuitable.

Data Protection

This website makes use of cookies in case you are being logged in. Furthermore, we also log visits to this website and use a tool to track web visits to our site in order to optimize the site for our visitors, and to maintain the security of this site. The tracking apparatus is part of our own installation, so at least we don't actively share such data with third parties. If you do not want to be tracked, you are free to block access to our tracking server, but regular logging will be unaffected.

Errors, Mistakes, Omissions

This website is only up for a very short time. If you find something you do not like, or if you are missing some functionality which was provided by our old website, please notify us, or simply cut us some slack and return in a few days. In the meantime, we strive to fill the gaps as soon as possible.
Thank you!
