This plugin will register the page 'Links' as a [special page?]. Admin users will then be presented with a form at the bottom of page 'Links' which will allow them to input a URL and optional title and description fields. The link will then be appended to the page.
Once the plugin is installed, log in as an administrator and navigate to the page 'Links'. You will see a form at the bottom of the page to add a link to the page.
