TikiWiki (http://tikiwiki.org/) could give you the pluggable authentication and control that you are looking for with integrated versioning capabilities and browser-friendly output (in fact many output options) I'm not sure whether it will match your requirements exactly, and I haven't been following the project for a while so you'll just have to check it out to get the current features.
Another project that I used a bit more recently was Seagull....(http://seagull.phpkitchen.com/). Seagull is an Object-Oriented PHP framework, with excellent documentation, and leverages the packages in PEAR. Although intended to be a framework first, it does include some nifty capabilities in the area of permissions, authentication and content management including documentation. One of the neat features that I liked about it was that if you structured your documents, you could actually output a pdf of the whole collection such that you could publish a 'print version' too. For support, this would be a possible revenue stream: free access to the online version one page at a time, searchable and easily navigable. And if you want to have a print copy around, to read offline, purchase the printed copy almost on demand. _______________________________________________ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss
