We would like to be able when writing notes (in the admin console) to notify other product managers of something that may affect them or they need to be aware of.
When responding to comments (in the end user console) we would like to be able to notify specific users that we have addressed their question or issue.
By using the @ followed by the user email, this should send them a specific email notifying them that something is important to them. This also would help us reduce noise of how many emails administrators currently receive.
