Usenet Junkie was a Usenet search engine and client program. It’s search service was built into a few other newsreaders. Usenet Junkie was probably wiped out by the switch to the NZB method of indexing, searching, and downloading from Usenet. The Usenet Junkie website appears to have gone off-line in late 2006.
A good replacement for Usenet Junkie is our SuperNZB Usenet downloader.
