Docpile is a PHP-based document management system that allows multiple people to share documents and keep track of revisions. Users can upload and download documents, grant per-file, -user, or -folder access privileges, and send notification emails when documents are being updated. Administrators can create access groups, each responsible for a different set of folders and users.
Make sure that the user access level is not 255. This level has some restrictions that were created for guest and public users. Also access level 0 is reserved for admins and they have access to everything regardless of permissions.
Styles: Right now you can change the css files, as well as the headers.inc.php file. However, I want to make it easier to have different themes. Any ideas and contributions are welcome.
If you have a style that you want to contrinute, please send it to me.
