From comments to Inbox: who sees what in a proofing workflow?

Besides literally starting a message thread with a project manager from a job info page, there is another step in Plint workflows which will automatically launch a thread with the project manager: adding a General comment on status change. This comment can also be made visible to other users. This example will explain how:

• Freelancer A completes a job in Plint Subtitler
• Freelancer A changes status and leaves a General comment
  
• Adding a General comment automatically creates an Message thread with Project manager
  • The thread is linked to the job
• An automatic notification email about this thread is sent to the PM as well
  • The thread includes the comment
• Another automatic email is sent to the owner of the child job
  • In this case Proofing, owned by Freelancer B
  • This email does not contain the General comment
• However, Freelancer B can see it under Track changes along with the Milestone for the status change
• Freelancer B completes proofing in Plint Subtitler
• On status change, Freelancer B set Approved to "No" and adds a General comment
• This comment also results in a Message thread
  • This one between Freelancer B and Project manager
• Each freelancer can only see their own threads
• Since the translation was not Approved, the parent job is reopened
