Just a small clarification:

* Any packager (i.e., any member of the packager group: https://admin.fedoraproject.org/accounts/group/view/packager) can (officially) review the packages of anyone, including of the not-yet-packagers. However, only the sponsors (i.e., sponsor members of the same packager group: https://admin.fedoraproject.org/accounts/group/view/packager) can approve the packages of the not-yet-packagers.

* Even the proven packagers (i.e., members of the advanced-packager group: https://admin.fedoraproject.org/accounts/group/view/provenpackager) can not approve the first packages of the not-yet-packagers. Again, only sponsors can do that. Proven packagers can commit into the Fedora package Git repository, for any package. Where as ordinary packagers can commit into that Git repository only for the packages they own.

Cheers
