Describe the problem you would like to solve
An Editor would like to find a way to view the Reviewers email address while sending the review request. Currently, only the Reviewer name is displayed. The Editors must go to the Activity log after the review has been requested to confirm this.

Describe the solution you'd like
Display email address of the reviewer beside their name to be able to quickly discern whether this email address is the most current.

Who is asking for this feature?
Requested by Journal Editors.

Additional information
Tried against 3.2 and 3.3

It would make sense to show the email already in the listing where you choose the reviewer.
