How to use Newsgroups?

Anyone here know how to use Newsgroups?

I just signed up at usenet.net

Can someone explain to me in laymen's terms how this thing works?

Clients, NZB files?

SeaMonkey is a great regular newsgroup client, but if you want to download large RAR and PAR files, you need a NZB client like SuperNZB.

Of course, you also need an NZB file, which which contains information about the file of interest (video or whatever) and is downloadable from an NBZ site. There are links to some of them on the techsono site.
Install SuperNZB, fill in your newsgroup data and browse to a downloaded NZB file on your hard drive, press the Import button to have SuperNZB search for and import files from the NZB file which interests you, and then the Start button to download and decode your file.

Thanks, man. I got it figured out now.

Boy, this place has slowed down a lot, hasn't it? I used to post here way back when and this place was busier than wall street.
