Discourse provides RSS feeds for all posts and for all categories and tags. Unfortunately, it’s not that obvious, so I’m writing it down here:
https://help.univention.com/posts.rss
→ this is the RSS feed for alle new posts
Additionally, you can append “.rss” to most URLs to get a specific RSS feed:
https://help.univention.com/c/ucsschool.rss
→ this is an example RSS feed for all new topics in the category UCS@school
https://help.univention.com/tags/docker.rss
→ this is an example RSS feed for all new topics with the tag “docker”
