I've been building a Facebook Events style event organizing system for the Fediverse. It's based on the simple, open source, privacy-respecting event organizing tool https://gath.io
The attached video is a work-in-progress preview and shows compatibility with Mastodon. My hope is to get it working with lots of software, including stuff like Friendica that supports events and calendars.

Also on the todo list is to add an Events tab to Hometown that keeps track of events you've RSVPed to. (For federation nerds: this will be driven by ActivityPub `Event` activities sent to a user's inbox after they've successfully RSVPed.)
omg this is cool, I only had to change one line of code and now my gath fork provides verrrry minimal Friendica compatibility! (the end time is the same as the start time, probably a bug on my end, but still, this is neat to see this working "for free" after implementing Event activities)
@mike Okay, cool. Do you send out an Accept/Event when I click the affirmative RSVP button on an Event I've received? I am not seeing anything POSTed to the inbox of the actor on my end when I RSVP from Friendica.
In here I see a sendContactAccept but not a sendEventAccept, for example https://github.com/friendica/friendica/blob/a8fa7e5187cbe24c2d69ed09cdbbe87e5fe5b8ef/src/Protocol/ActivityPub/Transmitter.php
@mike okay great! Is there a Zap instance that I can create an account on? I signed up for hubzilla but could not figure out how to send a follow request to an AP account (I'll read docs later this was just my initial attempt)
@mike I haven't successfully found a place to test from for zap or hubzilla, but I did get affirmative RSVP working with Friendica, which is using the same federation model you mention (Accept/Event). Can you try following @V_Yyi5YB7 -- you'll get an Event in your feed that you can RSVP "yes" to, and it should after a few minutes be reflected on the page. (If you go to https://events.tinysubversions.com/V_Yyi5YB7 you'll see that's a Friendica account that has RSVPed there)
Hometown is adapted from Mastodon, a decentralized social network with no ads, no corporate surveillance, and ethical design.
