Why do I rate a legacy component to 5 stars? Its easy because it is the only DMS for the Joomla CMS. There are a lot of very good download components for both J!1.x and J!1.5, but if you need a well written document management system with user access control and document check-out / check-in, there is only Docman. I use it since J!1.x and on most of my J!1.5 sites and never felt in trouble. It is easy to extend. For example on the site users can build icc profiles online and are getting the results automatically in their private Docman download area. Thanks a lot for docman and a look forward for the upcoming native versions. Please take the time you need to make it solid as docman has been in the past.
