Convert all external links into internal or nofollow links!
This plugin is a fork of the hijacked and vulnarable “WP No External Links” plugin.
The following critical issues have been fixed: 
– Removed Cross-Site Scripting vulnerability. 
– Removed backdoor injected into original plugin. 
– Fixed creation of the new <code>links_stats</code> table: added charset collation and table existence check. 
– Fixed “Specified key was too long; max key length is 767 bytes” error on creating <code>mask_links</code> table. 
– Added removing tables on uninstallation.
No External Links plugin is designed for specialists who care about the number of outgoing links that can be found by search engines. Now you can make all external links internal! Plugin does not change anything in website database – it just processes the output. Now you don’t need to worry about your page rank dropping because of spam bots. You write any kind of http link and it becomes internal, hidden or nofollow! Of course, all the links will still be usable.
To make the long story short, your links like “http://gmail.com” will be masked into 
“http://YourBlog.com/goto/http://gmail.com” – or 
“http://YourBlog.com?goto=http://gmail.com”

<h4>Known Issues</h4>
This plugin may conflict with your caching plugins, including Hyper Cache. Usually adding redirect page to caching plugin exclusions works fine.
If you disabled this plugin and still have links masked – check your chaching plugins.

The Outbound Link Manager monitors outbound links in your posts and pages, easily allowing you to add or remove a nofollow tag, update anchor texts, or remove links altogether.
The whitelist + blacklist functions mean you can also set rules around when a nofollow tag should be added.
<h4>Here’s what you can do:</h4>
<ol>
<li>Remove links. The original anchor text is kept in tact.</li>
<li>Add or remove the NoFollow tag. </li>
<li>Achieve the above in bulk by selecting numerous posts/pages or links.</li>
<li>Edit links. This gives you instant access to the whole link code, allowing you to add styles, targets or change the anchor text.</li>
<li>Add domains to the whitelist: all other links will be removed or nofollow will be added.</li>
<li>Add domains to the blacklist: all links to these domains will be removed or nofollowed, other links will not change.</li>
<li>Ignore posts/pages so that they won’t show up in the link list again. You can remove these from the ignore list through the options page.</li>
</ol>
This plugin is aimed at SEO managers who would like to monitor external links. It is also helpful to monitor external links if you are outsourcing your content creation.
