[Trac] Ticket Permissions

[Tom Schindl]

I'm not sure and maybe I've missed something but the permissions system 
at least for tickets is not very useful in my idea.
What the ticket system really needs is:
* Report => can report bugs and add comments
* Developer => can add comments on bugs and close them (modify state)
Have I missed something or is this not possible with trac? If it is not 
possible I'm afraid that I can't use it in our projects because what 
prevents me from anyone simply closing a bug?
