second for aCalendar+. been using the paid version for a few years now with a self hosted nextcloud instance. works great! works great with other calendars too (google, etc).

if you look at the function that gets the admins, then you can see that it’s ordered by the Published date, so I believe you can just update the Published date to earlier than the rest of the admins.

i believe they typically run as a service on a computer, monitoring the subreddit via the reddit api, the when it finds new stuff, it posts it onto lemmy.
