This is a plugin for WordPress.
It will disable the automatic
added to external links. You may want to do this if you have good spam
filtering for your comments, or if your blog is moderated.
Optionally you can also set a comment age limit for adding the attributes, or have them removed differently from comments left by registered users and other visitors.
Pingbacks and trackbacks are just different types of comments in
WordPress. This plugin will take care of all of them. You can also
choose not to remove
rel="nofollow" from some types of
WordPress 1.5 or later (including 2.x).
Download dofollow.php and save it in the
wp-content/plugins directory of your WordPress
installation. Activate the DoFollow plugin in
the Plugins admin page.
Once activated, the plugin provides a DoFollow subpage in the Options page. It will show you the current operating mode in addition to the configuration options.
