The iisue is having people use the platform. On Lemmy we are getting there :). Also I’ve seen some niche communities using forums still.

I see radicale recomended, but in what ways is it better than nextcloud? I moved to nextcloud for calendar due to syncing issues when sharing calendars. So far it seems to be fine, but this question got me wondering about what can be done better.

The only thing I’ve found that bothers me is that to add someone to the event he needs to also have nextcloud otherwise it gets weird.

Thats great news, i’ve been using joplin for years without knowing about Joplin server
