[xwiki-devs] notifications "start configuration"?

Hello xwikiers, the page at http://platform.xwiki.org/xwiki/bin/view/DevGuide/Notifications is really nice and shows a real nice pearl of XWiki. I did similarly and my notifier seems to run smoothly. I would like to know, however, what is the way to make sure that a notifier (an implementation of XWikiDocChangeNotificationInterface) is running at every restart of our XWiki. I tried to add the fullname of either the velocity (the "starter") or the Groovy pages into that line and restarting but my notifier didn't seem to have been running after that. What is the correct way? It should definitely be documented at the pircbot page. thanks in advance paul
