unPoster

Designed to make looking in giant newsgroups as easy as possible. Instead of waiting for millions of headers to download as with an old-fashioned news-reader program, the unPoster constantly scans your groups and keeps a list of the files available. If you leave the program running in the background, all that you need to do is select files to download from the unPoster's list. There is no other practical way to keep up with high-traffic groups. The program also works well with browsing smaller groups and supports yEnc. You can download several different files at the same time, and the program will automatically process PAR files, and extract files from RAR archives.
