Well, I'd like to think I'm not a stupid person but trying to host a #Fediverse instance the 'easy' way via using Yunohost was beyond me this afternoon.
The steps make it sound easy until the magic DNS diagnostics don't work for your registrar (Njalla), and your VPS company (Hetzner) doesn't open SMTP ports.
Meanwhile, Hostman wasn't accepting new sign-ups, and the only other Pixelfed hosting service I can find doesn't allow configuration of some basic admin settings.
