A forum moderator, often shortened to just mod, is a person granted special powers to enforce the rules of an Internet forum (message board) or electronic mailing list. Almost all moderators on all forums can move discussions to different sections of the forum, close discussions, edit the content of individual postings, answer questions (or help people with problems), and 'stick' discussions so they remain visible in their forum section even if no new postings are made to them. Different forums may give their moderators further powers, such as being able to block/ban people from the message board who are trolling or breaking the rules of the message board.
