That is very kind!
My main question is probably how do I introduce the topic in an interesting way to non-techy folks.
What's the best topic to start? What are some must known examples of how things go wrong?
Not exactly for me - I want to do a workshop about the topic as well! (and only have few days to prepare)
If I manage to get some slides together I'll gladly share them here!
I would reccomend any CalDav compatible Client like Fossify Calendar for Android or Thunderbird for Desktop or anything that comes with your Distro really.
Works offline without any special setup.
Syncing is the "tricky" part.
If you plan to self host Radicale comes to mind.
Otherwise you might want to look into Nextcloud as a service or Etesync for the privacy minded.
I use Translate You with DeepL as well. Some time ago it stopped accepting my API key. Now I use the free API which works fine. I didn't dig to deep but what changed with the API? 🤔
Klasse - Danke!
