Where are directory access, is there some special sort of access other than admin in order to upload a new version? For example, would someone have to be a 'site administrator' in order to upload the new versions?
My options at this point are
dashboard> write
dashboard> manage
dashboard> comments
I would imagine dashboard> manage would be the right button to push so far,
however, after that, my only options are
manage>posts
manage>pages
manage>links
manage>categories
manage>tags
manage>link categories
manage>media library
