Oops sorry, I meant your EDK2 "co-designated Package
Reviewer"

  R: Package Reviewer: Cc address for patches and questions.
     Reviewers help maintainers review code, but don't have push access.
     A designated Package Reviewer is reasonably familiar with the
     Package (or some modules thereof), and/or provides testing or
     regression testing for the Package (or some modules thereof),
     in certain platforms and environments.
