I've been pretty happy with Dokuwiki with a CMS template (DokuCMS). Used Dokuwiki in internal and external (with DokuCMS) sites. The editing is text based but not hard at all to grasp (I tell staff just copy the text from an already made page to use as the new page. The DokuCMS template is pretty well laid out so it can be modified to suit. Also the DokuCMS navigation menu is just another wiki page, so s/he can edit that via the wiki editor as well so adding sections/pages are no problem. http://www.dokuwiki.org/dokuwiki http://www.dokuwiki.org/dokuwiki http://www.dokuwiki.org/template:dokucms http://www.dokuwiki.org/template:dokucms
