[rt-users] Comment from user with rights

[Stephen Gower]

  I have a user who is not part of any group, but has User
  Rights for one queue and one queue only.  The rights he has are
   CreateTicket
   ModifyTicket
   OwnTicket
   ReplyToTicket
   SeeQueue
   ShowTicket
   
  He does not have CommentOnTicket, and yet, using the 
  web interface, he is able to (and often is) sending comments.
  
  Is this a bug, or does one of the other rights above allow him to
  comment on tickets in this queue?  How can I stop him?
