LysKOM is an online, text based, interactive discussion system sort of like a mix between Mail, News, IRC and a BBS system. It's modeled after the KOM system that was available to DECsystems running the TOPS-20 operating system ages ago. The web site for LysKOM is written in Swedish, but the README files on the FTP site are in English. Both the server and (some of) the client(s) can speak both Swedish, English and other languages. LysKOM is a client-server system. This project is the server software itself.
