Office Tournament is a tool for keeping track of office tournaments, such as foosball. You may enter data from the command line or from the CGI Web interface. It outputs all kinds of stats and even a nice chart if you use the Imager::Graph::Pie Perl library available from CPAN. It currently requires no database to run, but there are plans to migrate the text (flat file db) to MySQL.

The Anti-Spam SMTP Proxy (ASSP) Server project aims to create an open source platform independent SMTP Proxy server which implements whitelists, Bayesian, and virus filtering to help stop unsolicited commercial email (UCE). Anti-spam tools should be adaptive to new spam and customized for each site’s email patterns. This easy to use tool works with any mail transport and achieves these goals requiring no operator intervention after the initial setup phase.
