Is it possible to change this?

I am using Nuke 4.5.5 and forums 4.4.3

When I ran locally in a new install of DNN, I didn't have this problem.  Now, when users get to the Add/Edit post screen, they can see the side Site Navigation in the 'DNN-Blue with Left Navigation' skin, regardless of the Role they are in.  I just want the navigation to be hidden for registered users.

I'm thinking that I should just have to chagne the skin to one that does not have the nav, but I couldn't find anything related to changing the skin whatsoever.  Am I missing it somehow?

Any help with this would be greatly appreciated.

Thanks,

Josh

The only users with Edit Permissions are Administrators.  I tried different settings there and also on the Edit Forum menu to no avail. 

I did read the manual already before posting here... and also spent many hours searching the web and trying various settings...

No matter what, when a registered user gets to the Add/Edit Post screen, they see the Site Navigation on the left as if they were an Administrator in Edit Mode.

Is it possible to change the skin that is used?
