By default, Gerrit Code Review does not allow self-reviews. If you want to configure Gerrit Code Review to allow self-reviews, you must do so in the Gerrit Code Review prolog file, rules.pl. In new installations of GitCentric 2013.3, a copy of this file is installed to the /meta/config branch of the special All- Projects repository.
Working with the rules.pl prolog file is beyond the scope of this document. Refer to the Gerrit Code Review documentation for more information: https://gerrit-review.googlesource.com/Documentation/prolog-cookbook.html
