The previous website was built using Joomla 3, which is no longer supported. The transition to Joomla 4 proved to be very time-consuming, especially because we also had to switch to a responsive design at the same time. To keep the effort to a minimum, the following steps were taken:

• Change to static website (using Zeta Producer)
• Conversion from a German/English website to an English-only website.
• Simplification of this overview. Minor additions to the text of existing pages will no longer be recorded.
