[NTG-context] TeX in Czech?

Hi, a friend just asked for a LaTeX book in Czech to give a PhD student for their birthday. According to https://www.cstug.cz/informace/literatura/, there are only outdated TeX books in Czech. Is that true? Looking at the CSTUG page, I wondered why our ConTeXt meeting isn’t listed in https://www.cstug.cz/informace/zpravy/ (While TUG 2023 in Bonn is listed, BachoTeX 2023 also isn’t.) Sad.
