The duty of a MHF Moderator is to enforce forum rules and manage the day-to-day affairs of MHF as it applies to the stream of user contributions and interactions. The relative effectiveness of this user management directly impacts the quality of MHF in general, its appeal and its usefulness as a community of interrelated users. The unpleasant consequences that occur when this duty is neglected are readily observed at various other websites. All posts are subject to review by the MHF Moderators and Administrators. Moderators and Administrators reserve the right to edit and delete posts and close threads, issue Warnings and Infractions and perform any other actions and interventions s/he deems are necessary to perform his/her duty.
