It wouldn't be right to do this section without giving full credit to www.newzbin.com for the creation of NZB files and because i am a big fan of newzbins indexing service so i have decided to make the tutorial concerning NZB files using Newzbin. There are other ways and means of obtaining NZB files but for me there is no easier or better way.
Newzbin is by far the easiest to use and most comprehensive usenet indexing site, and at only a nominal fee per week (about 50 cents US or 35c euro) it's very good value for money.
you can use it's basic indexing service for free but to get the best from newzbin (and from usenet) then i recommend subscribing to their service, you will then get to use their NZB support. (amongst other features)

Work in progress
