Hi Bill,
Have you looked at Joomla and Drupal?
They are for site content management rather than just blogging. I have not used either but I am thinking about it. My impression is that the bare basics might be light, and then they are 'infinitely' extensible with extras: you can develop a big forum or a directory site or whatever you want (they say). All open source.
I originally choose Wordpress over Movable Type because people suggested it could be used for content management on a site, beyond just the blog aspect.
Seems to me, after looking into it, that I would actually be fighting it to do that. However, for a blog it was very easy and friendly.
I was browsing this forum looking for info on content management options when I noticed your post. Have to admit I am a bit scared of Joomla and Drupal because it seems like jumping in the deep end.
Just saw this related link at the bottom of the page: evaluation of Wordpress vs Drupal. Think I had better go and read all about it.

Good luck.
