sorry, the full article is coming up for me and I'm not a subscriber
Try reading more articles. Eventually you will get the request for registration.
Couldn't you just press the Close button?
NS will only let you read 3 articles - then it will ask you to register and you will be able to read another 7 in one month and then you need to PAY, since I normally buy the dead tree version this is just harassment!
It's a pretty weak paywall: Disable javascript, the article displays fine.
(Aside: Won't that approach - 'hiding' content from visitors - get them penalized by Google?)
