In a moderated newsgroup, only selected members have right to post a message directly on a virtual notice board, In a moderated newsgroup, when an ordinary member creates a new message, he first sends it to one of the members having the right to post a message on the notice board directly. The authorized member then checks the message to decide its appropriateness for posting. He does necessary editing to improve the message and then posts it on the notice board. The message now becomes readable. Main idea of a moderated newsgroup is to ensure quality of posted messages.
