sapka.pl is a Fediverse instance that uses the ActivityPub protocol. In other words, users at this host can communicate with people that use software like Mastodon, Pleroma, Friendica, etc. all around the world.
This server runs the snac software and there is no automatic sign-up process.

USER: snacAlso, I think it's important to remember that #snac also allows following hashtags by those RSS feeds provided by several Fediverse implementations (like Mastodon), avoiding the need of subscribing to a relay. E.g., you can add https://mastodon.social/tags/snac to the followed hashtags field, and it will periodically poll that RSS from the big instance and add to your timeline those posts tagged with #snac.
It only lacks auto-complete of handles and tags.
