That seems like a good point. I agree that Watching isn’t necessary, and Regular should be sufficient for all staff who aren’t immediately involved.
To add to that, the main reason I wanted other staff added was that we recently had to issue a warning to a user and he requested that all staff involved in the behind-the-scenes decision be included in the message. When sending the warning initially, I had assumed that other staff would be included automatically, so when I went back in I was surprised that wasn’t the case.
