    In the Name field, you enter the text that you want the link to display in the sidebar as the link. Under Web Address, if it an external link, you enter the URL of the other site, including the http:// designation that precedes a web site address. (An external link will not operate properly if you omit the .’http’ reference.)
    The Description is optional; if you fill one in, it appears as a tool tip when a user holds the mouse stationary over the link.)
    If you are linking to a page or a post that is elsewhere inside your own WordPress site, you will need to know the page or post ID number. You can quickly find the ID number for a post or a page by looking at the number that immediately follows the question mark in your browser address bar whenever a post or page is visible on the screen.
    Once you know this value, you place the following in the web address field of the Add New Link screen if it is a post, substituting your actual ID number for the value ‘123’ in the example:
    Post Title
    And  you place the following in the web address field if it is a page, substituting your actual ID number for the value ‘123’ in the example:
    Page title
    By default, all links appear in a category called ‘Blogroll.’ However, you can easily create new categories for your links, by choosing Links > Link Categories from the Dashboard, and defining the new category in the screen that appears. Then when you add a new link at the Add New Link screen, you can place the link in your newly defined category.

To Comment, or not To Comment? That is the Question...
    A decision that you will need to make regarding your site is whether or not you want to provide viewers with the ability to comment on your posts and / or pages.  If you look at any of the pages that you've created following this tutorial, you will see that each page has a comment area at the bottom of the page, where viewers can add comments about your posts or page content.  Depending on what you are using your site for, you may or may not want to provide viewers with this capability.
    Enabling (or disabling) comments is a simple matter, and you can do this for individual pages or posts, or globally for the entire site.  If you want to disable the ability to comment for an individual page or post, from the Dashboard, select 'All Pages' or 'All Posts' to display all of your pages or posts, hold the mouse stationary over the desired page or post name, and click Quick Edit. When the Quick Edit screen appears, turn off the 'Allow Comments' check box and click Update, to prevent comments on that particular page or post.
    To control comments at a more global level, throughout the site, go to the Dashboard, and choose Settings > Discussion . You'll see the Discussion Settings screen, shown here.

    This screen provides a number of options that control a reader's ability to add comments to your site.  You can disable all comments by turning off the check box labeled 'Allow people to post a comment on new articles.'  You can also require people to register with your site in order to post comments (people that register are added to the Users section of the Dashboard, and you can use options within that section to control their editing rights.) You can have your site notify you by e-mail whenever anyone posts a comment, and you can have comments held for approval by yourself or by someone else before the comment appears on the site.  If you plan on making use of the blogging aspect of WordPress and you want to give others the ability to comment, you should spend some time examining all of the options on the Discussion Settings screen.
    TIP: A sad fact of life in the WordPress world is that if you enable comments, you will find over three-quarters of the comments you receive to be spam. You’ll want to take preventive measures to cut down on the amount of spam comments received. You will
