article availability (Score 1)

okay, so I thought this was a reference to a learning guide about ethical hacking. interesting that after I log in to the site, I find I am not able to access the article because "You are not authorised to view this resource." I guess I'm not leet enough to qualify to be a hacker ... of any sort. or perhaps the original url is suspect? http://www.ethicalhacker.net/content/view/155/1/ or /2 wtf?
