We just updated our SDAC Related Content plugin to use WordPress plugin best practices and to improve the overall consistency of the plugin (moved the settings under the “Settings” menu. This is a great plugin for anyone looking for related functionality on WordPress, WordPress MU, or VIP hosting as it does not make any database changes and it uses caching.
Check out the forum for any support issues or leave any feature requests and we will do our best to add them into future releases.
