RelNoFollow 1.3

Scans posts for links and adds a rel="nofollow" to them. This is useful for avoiding getting dinged by Google and other search engines when spammers post garbage links on your site. If you happen to have "rel" defined for a link already, this extension will simply add "nofollow" to the attributes already there. This also removes any "empty" links: those with nothing or only spaces in them. Note that this does not work on URLs set in the user account page yet, but it will work for all posts.
