Please note!

Dear user, we have updated our website to the latest web standards more than a year ago and kept it up-to-date ever since. As we were aware that some of you had not yet changed their browser from the old Internet Explorer to a modern web browser, we kept this ‘legacy page’ that you are currently on alive for another year to give you more time to switch.

However, we will now drop support for the deprecated Internet Explorer on August 15, 2021 as this old browser is unsafe and does not support most modern functions that we rely on in our modern web interface.

Thus, we would kindly ask you to switch to a modern web browser. Thank you for your understanding.

Examples of modern web browsers are e.g., Microsoft Edge, Google Chrome, Firefox or Safari: Get modern web browser!
