Gerrit problem

Hi. I'm having a problem with Gerrit. When people try adding me as a reviewer, they see my name twice (aaviram@redhat.com) and when they try to add me as a reviewer they get the following message: "Amit Aviram <aaviram@redhat.com> does not identify a registered user or group" My account number is 1000627. Hope you can help :) Thanks a lot, Amit.
