These [author help->] pages are visible only to authors, and only when they are logged in. You don’t need any of this. If you just want to [write articles->wp-admin/post.php], all you need do is write them. You do not need to use any html. When you do want to add bold, italics, or an offset quote, the Quicktags buttons at the top of your Write Post page will let you do this.
The author help section will assist you in using some of the more advanced features of this site, such as [automatic smart links->adding smart links to articles], that make maintaining the site much easier.
