Welcome to the Fediverse! Get the fuck off mastodon.social as soon as possible
@annika Is there any simple way to set up Fediverse webfinger or similar service to use @mydomainname in handle without running dedicated server? I'd like to be part of bigger community than one user but still have the username that I can use forever and move around

I've not played with this myself but I think this is what jwz was trying to do in https://www.jwz.org/blog/2022/11/using-your-own-domain-as-a-mastodon-handle/ , so linking that in the hope it is helpful in some way, apologies if it isn't. (The answer there seems to be "no, it will only work as a redirect"?)
Using your own domain as a Mastodon handle

It seems that if you have /.well-known/webfinger redirect, you become discoverable on Mastodon using your own domain. E.g. following "@[email protected]" will now actually follow "@[email protected]", I think. But is there some way to make that mastodon.social address actually present itself as "@[email protected]" and make that be my canonical address? I would like that address to be the one that ...

@cougar Mastodon itself doesn't support this. The closest you get is a one-way alias on your own domain that points to your account elsewhere https://blog.maartenballiauw.be/post/2022/11/05/mastodon-own-donain-without-hosting-server.html
Mastodon on your own domain without hosting a server

Like many in the past week, I have been having a serious look at Mastodon as an alternative to Twitter.

What frustrates me is that it's entirely possible to write an external app to do post-migration. it wouldn't have to run on the same server or even be in the same language (Masto is written in Ruby). I just haven't had time...

(The one catch is that I'm not sure if the API allows backdating new posts -- but that could be ameliorated by adding a header or footer indicating that the post was migrated, and its original timestamp.)

@cougar @annika That would be quite a neat feature. Fediverse server virtual-hosting.
@andyd Takahē supports multiple domains, I haven't used it yet though
