Sorry kids, Emissary is very new and not yet ready for prime time.

So right now, the only way to get an Emissary account is to build and deploy it on your own servers, which means that only dedicated techies can use it right now. This will change in the future, and this page will become a place where you can find an Emissary server that you can use for your own Fediverse account.

In the meantime, Mastodon has a great list of servers where you can sign up.
