eThreads is a database-driven content engine written in Perl. Through modules it can support many different types of content with the same backend code. Included in the distribution is support for forums (eThreads' native format), directories, weblogs, and calendars. Look and feel is entirely customizable for each instance, and a plugin system exists to allow further functionality enhancements.

A mod_perl-based rewrite started in the summer of 2004. It got stable enough to support a blog in October. Hopefully it'll be ready for a release early in 2005.
