Do you own an international server? Want to have it in different languages, per player? You're lucky then! MultiLanguagePlugin (MLP) is here with a lot of cool features! This plugin uses a placeholder which will be replaced (dynamically, per player) with a message defined in the language file. More info below.
This plugin can hook into all plugins1 if you can change their messages.
