Sukiyaki was born out of what the author sees as a much needed improvement to current imageboard/BBS software. They're flaky, often have security flaws that users take advantage of, and worst of all, they have the same UI from the mid-nineties. It's time for an update! Sukiyaki visually organizes replies in threads so that it is clear who the reply is sent to. It is written using Django with its wonderful ORM, which helps reduce security vulnerabilities. It has been tested in production and is stable. It also includes a unique system for user-ranking of posts. Planned features include RSS updates for individual boards and threads, and there is a faster backend (Django-Treebeard).

The Newsroom is an addon module for the Falken BBS Software for Linux. The Newsroom allows the Sysop to post messages in a file called, newsroom.dat which is a standard ASCII type of file, and can easily be modified by the Sysop, or by anyone who has correct permissions set up. The messages that are posted by the Sysop remain to be displayed to everyone, until the Sysop elects to remove the message, or the messages from the datafile. With, or without any messages, a brief display of the header will appear when The Newsroom finishes up, and exits to the BBS.
