I talked about roles and permissions in DotNetNuke (DNN) in this post.

Sometimes you want to grant a role authority so users with that role can upload image files for their documents. Here is how you do it:

1. From the Admin menu, usually at the far right of the horizontal menu bar, pick File Manager;
2. You will see File Manager, Windows Explorer style. Underneath it is a section called Security Settings. This is where you grant view and/or write access to folders on the server.
