@Edent is this best done as a whole new server - creating a separate account to your "main" one for others to follow? I mean, I am sure it *has* to be because you can't just ask your existing account to publish arbitrary post metadata your client generates, or can't extend your existing client, but should clients/servers be more extensible to allow such experiments? I mean, it's not too hard to extend email like that.

In an ideal world, my main Mastodon account would let me attach location metadata much like Twitter does.
But, because it doesn't, I'm writing my own server.
It is just me scratching my own itch and proving it can be done.
