**This is not a feature**

Pivotal Tracker is a nice tool, however it lacks verbose permission and role functionality.  Currently Pivotal Tracker only defines 3 specific roles for projects which are:

 - Owner
 - Member
 - Viewer

Account roles can be viewed [here][1].  At this time, one cannot describe what a particular role should have access to/capability to perform.  For additional information on this request, you can see a discussion history of it [here][2].
