Tojo (formerly 31Journal) is a Web-based
collaborative journal system. It works in a manner
similar to a forum or BBS, but does not have a
concept of articles or threads, and instead
displays "entries" as part of a page, with one page
corresponding to a particular day. Other features
include themes, calendar, user preferences,
account maintainence, system configuration,
extensibility via plugins, and a modular system that
allows various database backends to be used.
