Good easy tool
Easy to configure once you grasp the idea of taxonomy, i.e. language that you attach different items (forums, stories, pages, polls, images, etc.) to.

The code looks very clean (though I haven't delved real deep) and the online community seems very nice.
Ported a site from phpNuke over rather easily and feel that I finally have a very secure site that can do what I want it to do.
