"Is Private" checked. Is it private? Not really.
One question: Could the "Is Private" be relabeled to say "Suspend E-mail Notification?" on the Action Log update?
If the "Affected User" has analyst access into the portal the "Is Private" is misleading, they can just access the system and see what the "Action Log" is. How is this 'private'? Just something that a new analyst is not going to understand or expect the first few times.
The system could also notify an analyst somehow before any automated notifications are submitted that if changes are applied or saved the following people will be notified.
