[rdo-list] unable to add second identity to https://review.rdoproject.org

Hi folks, When I signed into https://review.rdoproject.org with my GitHub account, there was no prompt to select my primary email address, and now RDO's Gerrit instance thinks my primary email is "ktdreyer(a)ktdreyer.com". I tried adding a second email address "kdreyer(a)redhat.com". The Gerrit UI says it sent a confirmation email... and then I never receive anything in my inbox. Who can fix this? - Ken
