I’ll admit, I am no flag expert but is the union Jack is made up of a few different flags that surely have to be older? Scottish saltire, st Georges cross.
My current set up is Eweka (usenet provider) and nzbgeek (indexer). I then run docker containers; nzbget (downloader), radarr, sonarr & lidarr (films, TV and music). I watched a few YouTube videos on how to set them up and have been very satisfied.
All the downloads automatically move to my NAS, and my jellyfin/Plex servers are pointed at them. The great thing about the “arrs” is that (if set up correctly) they rename and organise your media in a way that makes them easily identified by Plex/jellyfin, so all you have to do is say, I want movie “x” and then 20 minutes later you can watch it via Plex/jellyfin.
