Hi willjp and welcome to the PLUG forum. Until Covid we had monthly meetings, but we haven't had one for about two years. I'm not sure if we'll go back to that soon, or not. We have also had Zoom meetings, and last summer we had a few in-person outdoor meetings.
I have used Linux for home and work for about 10 years. Prior to that I was a Mac user, and I continue to use Mac hardware for desktop machines; set up to multi-boot. My distro of choice is Ubuntu, but I have used Mint, Arch and Manjaro in the past, and I played around with others. I also have a Raspberry pi 4B, which I used to play around with server software and other things. I use Linux for pretty much anything a typical desktop user does, plus a few other things related to research (like statistical analysis and reference organization). I did try a BSD once (PC BSD, which no longer exists), but just to play with. If we ever go back to in-person meetings I would love to have you demonstrate your setup.
