- Get an account with a Usenet provider. Eweka is one such provider.
- Install SABnzbd. Virtually all platforms are supported (Windows, Mac, Linux, etc). A Linux VM may be a reasonable choice of platform.
- An NZB search engine to find stuff to download. The NZBindex website is a free one.
You should also read this article from the folks at HTG.
- The NZBindex website provides no support or instruction, so you'll have to explore to find what you want. IMHO, the search box isn't particularly useful by itself. You may want to try narrowing down the list of Usenet groups you search over. Their names are descriptive; a.b.xxx = alt.binary.xxx, where xxx is a subject in which you might be interested.
- The HTG article lists a few alternatives to the NZBindex website. At this writing, they are pay-for-service sites.
- If you have a good Usenet provider, and you're using SABnzbd, you really only need to focus on the
NZB Search Engine. It's difficult to overstate its importance in terms of efficiency and results. The Usenet is a huge space, and there is a lot of junk in that space. This article lists, ranks & discusses several NZB Usenet search engines. - If you're keen on the history of things, you may find this Wikipedia article on the Usenet interesting.
