A friend is looking for a simple document management tool. (I searched here and found a similar question with no answers a little while back?). Docley (http://docley.com/) looks good but isn't released and thus well tested as yet. A full CMS like Joomla might work, but seems poorly focussed. KnowledgeTree is definitely overkill and the MS integration wouldn't be suitable. The community (free-gratis) versions of Magnolia-cms (http://www.magnolia-cms.com/home/magnolia-cms.html) and Alfresco (http://www.alfresco.com/community/) look like possibilities.
He requires versioning, notes to accompany the docs (eg abstract), limited checkout (it's a small firm so just a note of the "owner" is fine), ability to make files available to clients via the web. It would be used for legal and financial docs so it needs to be self-hosted with good security.
There is a low level of technical ability amongst his 5 workers.
Google Docs/Zoho Office would probably be fine if it were privately hosted and readily shareable. There is very little budget available.
We're both in the UK.
So, suggestions? What do you use?
Not sure if Mediawiki allows that.
