I plug my steamdeck into a USB dock, (for ethernet, video , etc) which has the Model M with a USB adapter.

Find an old IBM model M at a garage sale, or craigslist. Use it until the end of time.

Two. Two fries is a small.

I really, genuinely like Mobilizon, but the network effect is real, sadly, there aren’t nearly as many people there. I’d probably suggest doing both, and maybe the like-minded people that you find on meetup can follow on Mobilizon, and help that cause as well. Meetup has nothing special, except for lots of people that go there to find events.

An oversight on my part. Thank you for posting it. Sorry that we won’t cross paths there.
