Korallenriff is a program that collects input from different network sources and stores their data into one database. For example, it can receive POP3 mail or can fetch NNTP groups and store the received messages in a database. One can then, for example, use the database data within a Web site to display the latest postings of a newsgroup or to create an online mailing list archive.

You will be alerted only when the configuration finds your match. YAJNGI inspects a set of Usenet newsgroups using a perfect keyword, a regexp, or any phrases that you choose. It is multi-threaded and permits a different scan interval and actions for each group. It could be used to monitor newsgroups for your name, product, your favorite arguments, for downloading your favorite newest pictures or binary files, or any other topic of interest.
Remote HellaNZB GUI is a small GTK+ application to control your HellaNZB daemon. It's well integrated into your desktop. In a few clicks, you can manage your remote (or local) queue: add NZB files from your computer or from their newzbin.com ID, set priorities, see the progress of your downloads, etc. Unlike other similar projects, this one can truly add NZB files from your computer to your remote daemon; to do so, it copies them through SSH. For Remote HellaNZB GUI to work you need a running HellaNZB daemon; it does not configure it for you.
