Editing Comments
Navigate to the Post Manager, either through your Member Profile under Your Website Functions, or by clicking Manager Posts from the user side of the blog.
Click the Comments icon to view all comments. Click the Edit icon to modify a comment or Delete to remove a comment that may be inappropriate.
