What version are you running?
2.0.15
What's the URL of the page containing the problem?
N/A
What steps will reproduce the problem?
1. Add a reviewer
2. Reviewer is done & doesn't care about any more e-mails.
What is the expected output? What do you see instead?
It would be nice if there were an explicit CC button the user could uncheck to quite the e-mails for that review (i.e. they're uninterested in any remaining diff changes unless they were to get pinged explicitly via e-mail)
I could imagine wanting to be able to un-CC yourself from specific threads in a review. However, I suspect a single CC button for the entire review request (and all reviews) is probably the simplest & least ambiguous/confusing option.
