Edit Plugins ‹ BuildASite.US — WordPress: "Description ==
This plugin allows users of a WordPress MU site or WordPress 3.0 network to map their blog/site to another domain.
It requires manual installation as one file must be copied to wp-content/. When upgrading the plugin, remember to update domain_mapping.php and sunrise.php. Full instructions are on the Installation page and are quite easy to follow. You should also read [this page](http://ottopress.com/2010/wordpress-3-0-multisite-domain-mapping-tutorial/) too."
