I looked up radiosure.com with an online tool and that information says it originates from Moscow which explains the inability to reach it. It could be geoblocked, or just on blackout considering the state of world affairs. Which might explain the absence of Fonzy and other moderators from the different forums. I don't think he can get control of twitter account @radiosure even if he has access to internet. Source: over 2 years ago

You need a usenet provider like Fastusenet or whatever you prefer, then you need a client like sabnzb and then a search provider like NzbGeek. Source: 12 months ago

Get sabnzbd, this is kind of like your torrent client, you use this to download the .nzb files, there are many more clients if you prefer another one, here is the tutorial on how to setup SabNZBd. Source: about 1 year ago

If you use an NNTP provider, you also need sabnzbd. It integrates into Sonarr/Radarr and pulls NZBs from your NNTP provider(s) and reassembles them, including searching across other providers for missing parts, and using PAR files to repair broken files. Source: over 1 year ago

You're going to have a bad time if you don't use sabnzbd instead. Source: over 1 year ago

SABNZBD has a Linux version. Depending on your needs (and we'll leave it at that) you may need "other stuff" to go in conjunction with it. Source: over 1 year ago
