You already have a Mastodon account. You want to post on your web site, copy those posts to that account, and send responses back to your site.

Connect directly to the fediverse:

Your web site will be its own fediverse account, including its posts. Its username and instance will be your domain. This takes a bit of technical know-how.
...or, if you just want to check out the fediverse, try micro.blog or Mastodon. Or ask us more in chat!
