Dark Matter

Dark Matter is a highly opinionated domain mapping plugin for WordPress Networks, designed to work out of the box as-is with no setup. Unlike other plugins such as Donncha's "WordPress MU Domain Mapping" and WPMU Dev's premium domain mapping plugin, Dark Matter offers virtually no options beyond mapping individual domains.
