PIMPPA automates file downloading from newsgroups and FTP sites. Its especially designed for leeching pictures but can be used for any files. Filename-based heuristics and MD5 checksums are used for spam/duplicate prevention and automatic sorting of incoming material. The whole process is cronable. PIMPPA also includes a GNOME GUI and several commandline utilities for further processing and management of the kept files.
Bulletin Board News Server is a (relatively) quick NNTP interface for vBulletin. It reads directly from the MySQL DB and is therefore independent of the Web frontend. It doesn't alter read counters, but "forbidden names", name size limitations, user authentication, and anonymous posting (through a "usenet" user) are implemented. Registered users (either in the vboard or through a proprietary pw hash in the config file) can see the email addresses of others, as far as the owners permit it.
