[xwiki-users] Observer

How do I create an observer without adding a groovy code within a page?I saw this document: http://dev.xwiki.org/xwiki/bin/view/Drafts/GroovyNotifications but it requires code to be added within a page. Thank you.Allen _________________________________________________________________ New Windows 7: Find the right PC for you. Learn more. http://windows.microsoft.com/shop
