[Discuss] Opinions needed: wiki software

[Rich Braun]

I use Wordpress for this kind of CMS-oriented site. It has the user account and publish/private features you want, in a straightforward UI. It's definitely not just a blog tool, and probably has more open-source plugins than any other CMS or wiki system, but even without plugins it has the essentials of what you describe. Put that on your short list for consideration.
