I'm sure there are a few newsgroup users here and since it is an interesting topic, we might as well share tips for it.
For those who can't be bothered to google, a good description of what newsgroups are: http://slyck.com/ng.php
Who do you guys use to get access to usenet? I am on the Newshosting unlimited plan for $15 a month which charges me about £8.
What newsreader do you use? I like SAbnzbd from here http://sourceforge.net/projects/sabnzbd/
It will repair, extract and delete files automatically for you and scans directories for NZBs. You can also control it remotely which is awesome.
Finally do you guys use newzbin or do you get your nzbs from elsewhere? I use binsearch.info but I would like to know if there is anything better for free.
