An administrator can give comment permissions to user groups, and users can (optionally) edit their last comment, assuming no others have been posted since. Attached to each comment board is a control panel for customizing the way that comments are displayed. Users can control the chronological ordering of posts (newest or oldest first) and the number of posts to display on each page. Comments behave like other user submissions. Filters, smileys and HTML that work in nodes will also work with comments. The comment module provides specific features to inform site members when new comments have been posted.
