According to the Help Center of WikiAnswers, the mentoring program "matches up experienced site Supervisors (mentors) with newly promoted Supervisors (protégés) in an effort to provide a friendly, fun and worthwhile learning experience. Mentors provide solid support and guidance, garnered from their own hands-on experiences working as Supervisors within the WikiAnswers community."
For more information on the Mentoring Program, see the Related Link.
