Email should be okay, but I also joined Telegram
In the past few days I had technical issues with my email service provider. I will eventually write a summary of what happened. Everything should now be in order. I can send and receive messages reliably, without them mysteriously disappearing into the aether.
Since I already got the Signal app as a plan B for my communications, I am adding Telegram to the mix: https://t.me/protesilaos. I have updated my contact page accordingly.
Note that I am checking those messaging apps on occasion, but email remains my preferred medium of communication because of its interoperability.
