Team Reps are the people that do all the work behind the scenes. They make sure that the theme team runs like clockwork. Every one of them is here to help the reviewers do their jobs and the theme team function smoothly. Amongst other things, team reps make sure all the paper work is done and we keep other teams updated with weekly reports.
Theme moderators are experienced members of the theme review team who help out with different administrative tasks. Ranging from setting themes live to managing the queue or helping beginner reviewers.
