An icon can be added to the external links.
Unpack and upload it to the /wp-content/plugins/ directory.
Activate the plugin through the 'Plugins' menu in WordPress.
Here are some key features of "External Links":
· Process all outgoing links, rather than only those within your entries' content.
· You can use a class="noicon" attribute on links to override the link icon.
· Open outgoing links in new windows. Note that this can damage your visitor's trust towards your site in that they can think your site used a pop-under.
· Add rel=nofollow to the links. This is not very nice for those you're linking to, but useful to avoid PR leak.
· WordPress 2.8 or higher
