Just discovered fuzzylime CMS, formerly called PHP-Update. It's designed as a full featured Content Management System, with blogs and image galleries and polls and mailing lists. Unfortunately, they don't have a features page that lists what it can do.
The forum, however, is a separate system from the portal. You can find out more about the fuzzylime forum here
The forums do need a lot of work to be more user-friendly.
I was greeted by a bunch of blank lines where the content or some form of greeting should be. That's not really inviting.
