2) I've updated the server to Mastodon v2.4.0. Release notes at https://github.com/tootsuite/mastodon/releases/tag/v2.4.0
Some fun features, including four free-text fields you can show on your profile.
Hallo, new Mastodon users! Here on mathstodon.xyz we've got a couple of mathematical emoji: and . I'd love to add some more. If you can make a PNG image the same size as those, send it to me and I'll add it. Faces of famous mathematicians are an easy place to start; could we have some shapes, polyhedra, or other mathographics too?

I wonder if some crazy mathematician ever thought of talking to a number as if it was a friend... (Because numbers are friends?)
oh, you like Mikhail Gromov? name five of his papers
Genuinely assumed this was about Prince William and really couldn't work out what the banks could possibly be doing.
Another attempt at setting up a mastodon development environment, another dismal failure.
