Newzbin V3 is a indexing service and a usenet search engine for Usenet files!
They have a free and a paid service to offer.
The premium service is $0.60 a week.
Unfortunately they close their doors from time to time and you need an invitation of an existing member.
With the premium membership you can search their usenet database, get information of available downloads and their nfo’s.
Nfo’s are little text files which contain all information about the uploaded file like quality, release date, size, uploader etc.
When you’ve chosen a file you want to download, they offer what they call a NZB.
A file which tells your newsreader about where the file is located (in which newsgroup it was posted) and how many parts need to be loaded!
Unfortunately Newzbin V3 stopped their services!
