Now that I’m done traveling I’ll actually be able to respond in a timely way to people who were interested in trying Polymaths Pages, the free static hosting I’m now providing to members on my instance.
Just visit https://polymaths.page for instructions and send me (here or via email) an SSH public key and the names of any custom domains you want to use, and I’ll get you set up. I’m happy to help if there is any confusion or issues.
(Even if you don’t plan to significantly use it to host your main sites, you’re welcome to set it up to claim your <username>.polymaths.page subdomain and put something silly up there, like I did)
