[xwiki-users] Registering an event listener automatically

Hello, I need to find the best way of registering an event listener automatically on wiki startup. Right now I have to manually register the listener in a manner similar to the one illustrated in the Groovy Notification Tutorial (http://platform.xwiki.org/xwiki/bin/view/DevGuide/GroovyNotificationTutorial). Thanks in advance for any help. - Joshua
