To the right of each forum title are Modify and Remove buttons. Pressing the Remove brings up a box asking you to confirm that you actually want to delete the selected forum. If you choose OK , the forum is permanently deleted, and all messages are lost. The Modify button allows you to change the forum attributes you set when the forum was initially created. Additionally, you may set the privileges of each user from this screen.
Administrators are able to modify and delete messages and forums.
Generally, only instructors or teaching assistants would have administrator status, which is set by the Admin button. Students should usually have Normal access. To prevent a user from posting to the discussion board, you may highlight that user's name in the list and select the Block button. To remove this restriction, highlight the user's name and select the Unblock button. To accept the changes you have made to the forum, select the Submit button in the lower right corner.
