You might have seen few WordPress blogs linking to external websites through any of the top page navigation links. For e.g. ifthere is a sub domain like say forums.yourwebaddress.com, it would be appealing and easy if linked through the top page Navigation bar. Here I introduce a plugin called Page Links To that can link any WordPress page or post category to an external website, sub domain or link. WordPress 2.8 users can install this plugin via add a new plugin option from the dashboard. After installation, create a new WordPress page and name it as per your requirement.
Scroll down over post editor.
Here you will see a widget as shown below.
Enter the website, sub domain or external page to which the WordPress post is to be redirected, and publish the post. By default links are attached with a 301 permanent redirected tag. You may change that through the settings.
