It's a module made by english spoken people for english spoken people (futhermore who don't need any advanced features).
Sorry it didn't suit your needs. This is why it is a free add-on.
Support is very good and reactive.
Only one regret : the component is not Joomla 1.5 native
Thanks for your nice review . We are waiting for docman to release the version which works with Joomla 1.5 native . Once Docman works with Joomla 1.5 native, Our extension will be ported to Joomla 1.5 native , too .
