I have a few issues I need to work my way thru
(1)   DotNetNuke Roles and related Security Policies
I have settings in web.comfig specific to admin,registered and Guest.  IN DNN I have three defined roles - Administrators, Registered Users and Subscribers.   I'm assuming the  NukeEdit4 settings for  Guest apply to  Unregistered users - how do I set specific web.config settings for 'Subscribers' , as I want them to have  different settings to 'Registered Users'.

(2) Access to Folders
In admin.config ( and in the other .config files in Configuration\Security folder )  the relative path for manipulating the folder contents for images/flash/media is set to ~/uploads  .  This setting does not seem to take - using the Image Gallery for example gives the user access to the portal root.  Does 'uploads' refer to something defined elsewhere, or is it intended to be a folder name?
Note in web.config I have set UseDNNRootImageDirectory=true .

(3) Member Specific Folders
How can I provide a member specific folder, and thereby prevent Registered Users for manipulating images uploaded by other registered users?

Thanks in advance
